✦ Synopsis

The rotationally resolved absorption spectrum of LiAr due to the transition A 211 + X 2x has been investigated by laser spectroscopy producing the molecules in a supersonic jet beam. Vibrational levels with u = 0,.

,3 and 11 = 5,. . ,9 have been observed up to now for the X *2 and the A *II state, respectively. The XZ interaction potential has been determined by means of a quantum mechanical method using a Hartree-Fock di:persion function. For the well-depth and equilibrium distance of XC we obtain De = 42.5(1.2) cm-De = 925(40) cm-', R, = 2.48(6) A. ', R, = 4.888(U) A. Our preliminary results for the A *KI state are:

The A 2 ⌸-X 2 ⌺ ϩ transition of 174 Yb 35 Cl and 172 Yb 35 Cl has been rotationally analyzed for the first time. Doppler-limited laser excitation spectroscopy with selective detection of fluorescence was used to obtain spectra of the 0 -0 and 1-0 bands with a measurement accuracy of approximately 0.
