Abstract
A systematic experimental and theoretical studies of simple Ac and Ln containing molecules is one avenue for garnering insight into element-specific ligationb . Here we report on the high resolution (∼30 MHz) laser induced fluorescence (LIF) spectra of supersonic cooled molecular beam of ThCl produces in the reaction of laser ablated Th with an Ar/CCl4 mixture. The present work builds on the recent LIF, dispersed fluorescence, and REMPI study of the Heaven and Peterson groupsc . Analysis of a band near 550 nm has been assigned as the [18.2]1.5-X2Π3/2transition. Observed doubling the lines has shown to be caused Ω-doubling in the upper state. No 35Cl(I=3/2) hyperfine splitting was observed. Progress on recording the electric dipole moments and magnetic g-factors will be reported. Interpretation of the spectrum is based, in part, upon previously published electronic structure prediction and a simple molecular orbital correlation diagram.
