Rotationally resolved infrared–ultraviolet double-resonance effects have been observed in D2CO vapor by using pulsed radiation from a The infrared laser pumps CO2 laser and a tunable dye laser. D2CO molecules in the ν4 rovibrational band, and subsequent excitation by the dye laser in the 365-nm 410 vibronic band is detected by fluorescence at 420 nm. The results consolidate assignments from high-resolution absorption spectra and yield estimates of rotational-relaxation rates.
