What is Gaussian 09?
Gaussian 09 is the latest version of the Gaussian series of electronic structure programs, developed by Gaussian, Inc. It was released in 2009, replacing Gaussian 03. Gaussian 09 is based on the fundamental laws of quantum mechanics, and it can predict the energies, molecular structures, vibrational frequencies, and molecular properties of molecules and reactions in various chemical environments. It can also model spectra, solvent effects, thermochemistry, photochemistry, and many other phenomena. Gaussian 09 can handle both stable species and compounds that are difficult or impossible to observe experimentally, such as short-lived intermediates and transition structures.
Features and capabilities of Gaussian 09
Gaussian 09 has many features and capabilities that make it a powerful tool for electronic structure calculations. Some of them are:
It supports a wide range of methods, such as Hartree-Fock (HF), density functional theory (DFT), post-HF methods (MP2, MP4, CCSD(T), etc.), semi-empirical methods (AM1, PM3, etc.), molecular mechanics (MM), ONIOM (hybrid QM/MM), etc.
It has a large collection of basis sets, such as Pople's split-valence sets (6-31G*, etc.), Dunning's correlation-consistent sets (cc-pVDZ, etc.), Karlsruhe's segmented sets (def2-SVP, etc.), Jensen's polarization-consistent sets (pc-1, etc.), etc.
It can perform various types of calculations, such as single-point energy calculations, geometry optimizations, frequency calculations, transition state searches, reaction path following, potential energy surface scans, population analyses, natural bond orbital analyses, electrostatic potential analyses, etc.
It can calculate various molecular properties, such as dipole moments, polarizabilities, hyperpolarizabilities, magnetic susceptibilities, nuclear magnetic resonance (NMR) shielding tensors, nuclear quadrupole coupling constants (NQCCs), electron spin resonance (ESR) g-tensors and hyperfine coupling constants (HFCCs), etc.
It can simulate various spectra, such as infrared (IR) spectra, Raman spectra, ultraviolet-visible (UV-Vis) spectra, circular dichroism (CD) spectra, nuclear magnetic resonance (NMR) spectra, electron spin resonance (ESR) spectra, etc.
It can model various solvent effects, such as implicit solvation models (PCM, COSMO, SMD, etc.), explicit solvation models (continuum solvation model with discrete solute-solvent interactions), implicit and explicit solvation models).
It can handle various types of molecules, such as organic and inorganic molecules, radicals, ions, transition metal complexes, organometallic compounds, biomolecules, etc.
It can deal with various types of systems, such as isolated molecules, clusters, periodic systems (crystals, surfaces, polymers, etc.), excited states, spin states, etc.
It can run on various platforms, such as Windows, Linux, Mac OS X, etc.
It can utilize various parallelization techniques, such as shared-memory parallelization (SMP), distributed-memory parallelization (DMP), and mixed parallelization (SMP+DMP).
As you can see, Gaussian 09 is a very comprehensive and flexible software that can meet the needs of many researchers and practitioners in the field of electronic structure calculations. However, Gaussian 09 is not a free software. It requires a license to use it legally and properly. The license fee depends on the type and size of the license, the number of users, the type of institution, etc. For more information about the license and pricing of Gaussian 09, you can visit the official website of Gaussian, Inc.
Applications and benefits of Gaussian 09

Gaussian 09 is a very useful and valuable software that can enhance the scientific knowledge and innovation in various domains. It can also save time and money by reducing the need for expensive and time-consuming experiments. However, Gaussian 09 is not a magic tool that can solve any problem automatically. It requires a good understanding of the theory and methods behind it, as well as a careful selection of the appropriate parameters and options for each calculation. It also requires a critical analysis and interpretation of the results obtained from it. Therefore, Gaussian 09 should be used with caution and responsibility by qualified users who have sufficient background and experience in quantum chemistry and computational chemistry.
What is a torrent?
A torrent is a file that contains information about other files that are distributed over a peer-to-peer (P2P) network. A P2P network is a network where each computer (called a peer or a node) can act as both a client and a server, sharing files with other peers without the need for a central authority or server. A torrent file does not contain the actual data of the files it refers to, but only their names, sizes, checksums, locations, etc. A torrent file also contains information about the tracker, which is a server that helps peers to find each other and coordinate the file transfer process. A torrent file usually has an extension of .torrent.
How torrents work
To download files using torrents, you need a special software called a torrent client. A torrent client is a program that can read torrent files and communicate with other peers and trackers in the P2P network. Some examples of popular torrent clients are BitTorrent , uTorrent , qBittorrent , etc.
The basic steps to download files using torrents are:
You find a torrent file that corresponds to the files you want to download. You can find torrent files on various websites that host them, such as The Pirate Bay , Kickass Torrents , 1337x , etc.
You open the torrent file with your torrent client. The torrent client will contact the tracker specified in the torrent file and request a list of peers that have some or all of the files you want to download.
and decentralized way. BitTorrent also allows peers to upload pieces of files to other peers while they are downloading, creating a fair and cooperative system.
You finish downloading all the pieces of the files from the P2P network. The torrent client will verify that the pieces are complete and correct, and then assemble them into the original files. You can then open and use the files as you wish.
To upload files using torrents, you need to create a torrent file that contains information about the files you want to share, and then upload it to a website that hosts torrent files. You also need to keep your torrent client running and connected to the P2P network, so that other peers can download pieces of your files from you.
Advantages and disadvantages of torrents
Torrents have some advantages and disadvantages compared to other methods of file sharing. Some of them are:
Advantages
Disadvantages
They are fast and efficient, as they can download files from multiple sources simultaneously.
They are resilient and reliable, as they can resume interrupted downloads and handle corrupted or missing pieces.
They are scalable and adaptable, as they can handle large and popular files without overloading the servers or the network.
They are free and open, as they do not require any registration or subscription to use them.
They are illegal and risky, as they can violate the intellectual property rights of the owners of the files, and expose the users to legal actions or malware infections.
They are unpredictable and inconsistent, as they depend on the availability and quality of the peers and trackers in the P2P network.
They are incomplete and inaccurate, as they do not guarantee that the files are authentic, original, or safe to use.
They are selfish and unbalanced, as they can create a situation where some users download more than they upload, creating a free-rider problem or a tragedy of the commons.
As you can see, torrents have some pros and cons that you should consider before using them. You should also be aware of the ethical and legal implications of downloading or uploading files using torrents, and respect the rights and interests of the creators and owners of the files. You should also use a reputable and secure torrent client, and scan your files for viruses or malware before opening them.
