GaussView Tip: Modifying Spectra Displays

GaussView has the capability of displaying a variety of predicted spectra. Here is an example from an ROA calculation: It is quite common to want to customize such plots. GaussView provides a variety of options for doing so. Most are reached from the plot context...

GaussView Tip: Adding Hydrogens Selectively to a Protein

Many people don’t realize that GaussView can add hydrogen atoms to all or part of a protein input from a PDB file. In doing so, it uses the standard placements for filling out the valences of the various component amino acids. In addition, GaussView can also add...

Gaussian 16 Frequently Asked Questions

How do I generate Natural Transition Orbitals?   The TD-DFT method in Gaussian makes it practical to study excited state systems since it produces results that are comparable in accuracy to ground state DFT calculations. Sometimes, characterizing the specific...

Gaussian 16 Frequently Asked Questions

I optimized a structure, then calculated the frequencies for it. The frequency calculation showed the structure was not converged even though the optimization completed. Is my structure reliable? The structure you have is likely not reliable and can lead to incorrect...
