How to Download and Install Gaussian 09W 9.5 Revision D.01 for Windows

Gaussian 09W 9.5 Revision D.01 is a powerful software for computational chemistry that allows you to perform various types of calculations on molecular systems. It can handle a wide range of methods, properties, and performance enhancements, as well as support for NVIDIA GPUs on Linux systems[^1^]. If you are looking for a way to download and install Gaussian 09W 9.5 Revision D.01 for Windows, here are the steps you need to follow:

Download the Gaussian 09W 9.5 Revision D.01 setup file from a reliable source, such as this link. The file size is about 473 MB and it is compatible with both 32-bit and 64-bit architectures[^1^]. Make sure you have enough free space on your hard disk and a stable internet connection.

Extract the rar file using a software like WinRAR or 7-Zip. You will get a folder named Gaussian_09W_9.5_Revision_D.01 that contains the installation files.

Run the setup.exe file as administrator and follow the instructions on the screen. You will need to accept the license agreement, choose the destination folder, and select the components you want to install.

Wait for the installation process to complete. It may take some time depending on your system specifications.

Once the installation is done, you can launch Gaussian 09W from the Start menu or the desktop shortcut. You will need to enter your license information when prompted.

Congratulations! You have successfully downloaded and installed Gaussian 09W 9.5 Revision D.01 for Windows. You can now use it to perform various types of calculations on molecular systems and explore new areas of chemistry.

If you need more information about Gaussian 09W, you can visit its official website at You can also find the citation information for Gaussian 09W at If you use Gaussian 09W in your research, please make sure to cite it properly according to its documentation[^3^].

In this article, we will show you some examples of how to use Gaussian 09W 9.5 Revision D.01 for Windows to perform different types of calculations on molecular systems. We will assume that you have already downloaded and installed Gaussian 09W as described in the previous section.

Example 1: Single Point Energy Calculation

A single point energy calculation is the simplest type of calculation that Gaussian 09W can perform. It calculates the total energy of a molecular system at a fixed geometry using a specified method and basis set. To perform a single point energy calculation, you need to create an input file that contains the following information:

The route section: This specifies the type of calculation, the method, the basis set, and any other options you want to use. For example, if you want to calculate the energy of water molecule using the Hartree-Fock method and the 6-31G basis set, you can write:%nproc=4%mem=1GB# HF/6-31G SPThe first two lines are optional and they tell Gaussian how many processors and how much memory to use. The third line is the route section and it starts with a # sign. The SP keyword stands for single point.

The title section: This is an optional section that allows you to write a descriptive title for your calculation. For example, you can write:Water molecule energy calculation

The blank line: This is a mandatory line that separates the title section from the next section.

The molecular specification section: This specifies the molecular geometry, charge, and multiplicity of your system. For example, if you want to use the standard geometry of water molecule with zero charge and singlet multiplicity, you can write:0 1OH 1 r1H 1 r2 2 a1 a474f39169
