✦ Synopsis

The (0 -0) band of the B ˜2A 1 -X ˜2A 1 transition of CaOCH 3 at 565 nm has been recorded and analyzed at Doppler limited resolution (FWHM ϭ 0.005 cm Ϫ1 ). The molecule was generated using a laser ablation/molecular beam source in which a solid calcium rod was ablated and a mixture of argon seeded with a few percent of methanol was used as the carrier gas. The rotational analysis of the band is consistent with a linear Ca-O-C geometry in both electronic states. Values for the spin-rotation parameters are determined for the excited B ˜2A 1 state.

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
