Spectroscopic Studies of Gas-Phase ArCH(D) Van der Waals (vdW) Complexes: II. Observation and Analysis of B-X Electronic Transitions of ArCD.

Abstract

The ArCD van der Waals (vdW) complex has been generated in the gas phase by the 248-nm photolysis of CDBr3 entrained in a supersonic jet of argon. Rotationally resolved spectra associated with the complex have been observed by laser-induced fluorescence in the vicinity of the CD B(2)SIGMA- X(2)PI(1,0) band near 366 nm. Bands at 27310.7 /cm and 27327.8 /cm are rotationally analyzed using computer simulations and assigned as transitions to the B state (1,0 (sup 0),0) and (1,1(sup rho) ,0) vibrational levels, respectively. The vibronic structure of the ArCD excited states has also been analyzed using a model based on hindered internal rotation. The results are compared to those reported for ArCH.
