Cheap level done analytic check agrees
Harmonic frequencies at the cheap level (deck v1: B3LYP and ωB97X, 6-31G*, at the B3LYP geometry)
42 vibrational modes; imaginary modes negative. Shift = ωB97X − B3LYP.
Band heights are not computed for this molecule yet (no dipole derivatives); positions only, at unit height. High wavenumbers on the left; the table below is the same data.
