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.
