XIII.F.2. (III.B.7.b.) (IV.C.7.) (XVIII.B.2.) |
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
B3PW91/cc-pVTZ
Calculated values were scaled by 0.9616.
