title: Laser Excitation Spectroscopy of the &Btilde;2A1-&Xtilde;2A1 Transition of the CaOCH3 Radical.
abstract: The (0-0) band of the &Btilde;2A1- &Xtilde;2A1 transition of CaOCH3 at 565 nm has been recorded and analyzed at Doppler limited resolution (FWHM = 0.005 cm-1). 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 &Btilde;2A1 state.
