A new diode laser-based spectrometer operating at wavelengths close to 1 mm has been constructed for transient absorption measurements in the gas phase. Using a dual beam detection system for noise cancellation, the minimum detectable absorption was found to be 1 1 10 04 in 0.5 msec. The sensitivity

The \(S_{0}-S_{1}\) electronic band spectrum in biacetyl arising from the activity of the methyl torsion modes was simulated from RHF/UHF ab initio calculations. A fit of the calculated band spectrum to the cold-jet fluorescence excitation spectrum provided an assignment of the major bands and the l
