Dear colleagues,
I'm trying to obtain thermochemistry data, like enthalpy, entropy and Gibbs
energies correction, same analysis as gaussian does on the Freq calculation.
I tried with VIBRATIONAL_ANALYSIS using THERMOCHEMISTRY, however I'm not
able to obtain the entropic contribution and the final Gibbs energy.
Is some information missing on the input?
Please find attached below the input:
