The Fluorescence Excitation Spectrum of HCO &Btilde;2A'-&Xtilde;2A', 000 Band
The rotationally resolved laser-induced fluorescence spectrum of the HCO &Btilde;2A'-&Xtilde;2A' transition in the 000 band is observed under thermalized conditions. The formyl radical is produced from acetaldehyde photolyzed at wavelengths 310 or 308 nm. Some spin-splittings of the spectra are resolved. About 988 transitions to Ka' </= 3 and N' </= 24, approximately 94% of the observed lines, are assigned in this work including weak DeltaKa = &plusmn;2 transitions that become allowed because of the effects of axis-switching.
