摘要：

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