For pyridine in methanol, the errors in the frequencies are mostly below 10 cm results in a small pseudo-rotational contribution in normal mode 24, i.e., the seventh-lowest frequency mode. This may explain the high frequency and Raman intensity errors associated with this mode. The angular deviations are relatively small for all normal modes except the four lowest frequency modes. This is surprising when considering that the RMSD between the QM and QM/MM geometries is larger than the one for pyridine in methanol, where the angular deviations were substantially larger.
