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.
