Abstract

Infrared-ultraviolet double-resonance spectroscopy shows that the high rate of vibrational energy transfer between the ν₆ and ν₄ vibrational modes of D₂CO in D₂CO/D₂CO collisions is paralleled by efficient transfer in D₂CO/N₂O collisions. This implies that the mechanism of collision-induced ν₆→ν₄ transfer in D₂CO is predominantly intramolecular, in which vibrational excitation remains within the state-selected species, rather than intermolecular.
