Abstract

A novel infrared/ultraviolet double resonance (IRUVDR) technique, involving stepwise molecular absorption of pulsed 10.6μm CO2 and cw 441.6 nm HeCd laser radiation and detection of the resulting luminescence, is used to monitor energy transfer processes in biacetyl vapour. The infrared-induced variation in the intensity of biacetyl fluorescence at 460 nm is attributed to a specific hot band and subsequent vibrational equilibrium within the ground electronic state. Infrared fluorescence (6μm) and IRUVDR-induced phosphorescence (510 nm) have also been observed.
