2a) C2v point group with 1A1 ground state and 1A2 excited state resulting from promotion of b2 oxygen lone pair electron to \pi* of C=O bond.
The reducible representation on the vibrations of both states are \tauvib= 3A1 + 2B2 + B1
As fro...
Homework Statement
The first vibrational band in the absorption spectrum of H2CO is at 28871 cm-1. The first two bands in the emission spectrum (from v'=0 level) lie at 27021 cm-1 and 24687 cm-1.
Explain these observations. Determine the band origin of the electronic transition and the...
