✦ Synopsis
The harmonic vibrational spectrum of was calculated using density functional theory at the B3LYP and LDA C 70 levels using both 6-31G* and 3-21G basis sets in symmetry. The calculations were performed analytically by D 5h solving the coupled-perturbed Kohn-Sham equations. The calculated vibrational wavenumbers are in very good agreement with available experimental data. Basis sets including polarization functions are required to describe certain modes accurately.
