How to get Morse potential parameters for a particular normal mode?

I am working with acetone molecule and have done frequency analysis(both harmonic and an-harmonic). I want to fit c=o stretching mode to Morse potential. Is there any way to get the Morse...

How to get anharmonicity constant value from gaussian? Also what theory is encoded in software to calculate anharmonic frequencies?

I have done anharmonic frequency calculations in Gaussian09.(for acetone). At the end of the output file I can see the anharmonic frequencies. I do not see anharmonicity constant value(for...

Why there is no change in energy of Hydrogen(atom) when field is applied using gaussian software compared to when no field is applied?

I have done SCF calculation for hydrogen atom and in the second job I did the SCF calculation on hydrogen atom with field of 0.05 a.u in a particular direction, but there is no change in energy...
