You are here: Calculated > Vibrations > Bad Calculations > Bad vib. Calc. vs exp. OR Resources > Bad Calculations > Vibrations > Bad vib. Calc. vs exp. |
Calculated frequencies that differ from experiment by more than 400 cm-1 or have a ratio with experiment outside of 0.7 to 1.2 are listed
Calculated vibrational frequencies ("theory" in table) are calculated at
CCSD(T)=FULL/aug-cc-pVDZ
Calculated values were scaled by 0.9712.
