Dear Tian,

But I need the frequency values and the thermodynamic quantities G and H, although they are not displayed in the output.

Dear Tian,

I would like to perform a frequency calculation for a molecule that has already been optimized, using Gaussian.
The keywords I used are:
#p freq mpw1pw91/6-31g(d) scrf=(iefpcm, solvent=dichloromethane)

However, the calculation gives me this error.
What should I do?

Thank you in advance

Dear Dr. Tian,

Is there a simple program or script to perform theoretical calculations at high pressures using the XP-PCM model?


Thank you.
