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 B2SIGMA- X2PI1,0 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 1,1sup 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.
