FIRST OBSERVATION OF RE-VIBRATIONAL TRANSITIONS OF THE SIC RADICAL BYINFRARED LMR SPECTROSCOPY

Re-vibrational transitions in the (1-0) band of the electronic ground state X (3) Pi of the SiC radical have been observed with high accurac y using CO2-Faraday laser magnetic resonance (LMR) spectroscopy. The m olecule parameters of this electronic state were determined in a nonli near least-squares fit including all relevant experimental data of ear lier work. No indication for a perturbation by other electronic states could be found. For the band origin of the fundamental band we obtain ed 953.32062(27) cm(-1). (C) 1997 Elsevier Science B.V.
