Abstract

A laser excitation spectrum of the (0,0) and (1,1) bands of the CaF A2Π-X2Σ system has been recorded and all 12 rotational branches assigned on the basis of laser induced fluorescence measurements. Microwave optical double resonance (MODR) measurements were also made on several low-J transitions to obtain precise spectroscopic constants of the X2Σ state. The present set of molecular constants for both the A2Π and X2Σ states represent a vast improvement in precision over previously reported values because of the larger number of line position measurements and the use of a more reasonable Hamiltonian. The excellent agreement between the rotational constants derived from the optical and microwave measurements fully validates the assignments. Important derived constants are listed below (in cm-1) with 95% confidence limits in parentheses.
