Abstract
The frequencies of the nu(CO) bands of W(CO)(5)L (L = pyridine and pip eridine) in the lowest ligand field (LF) excited states have been obta ined by fast time-resolved IR spectroscopy of the species dissolved in low-temperature glasses, and the shifts from the ground state indicat e that the C-O bonds lengthen on excitation, contrary to the interpret ation of the pre-resonance Raman spectroscopy on the ground state.
