Abstract
Electronic spectra and predissociation dynamics for the CN-Ne van der Waals complex are reported. From an analysis of the bands associated with the CN B-X transition, we conclude that the equilibrium geometry of the complex is `T'-shaped in the ground state, and linear in the excited state. Electronic and vibrational predissociation of CN(B)-Ne was found to be too slow to compete with radiative decay. Excitation spectra for the CN-Ne A-X transition were strongly influenced by predissociation processes. Two channels were characterized for CN(A2$PRD, v equals 3)-Ne. One was spin-orbit induced (CN(A2$PRD1/2, v equals 3)-Ne yields CN(A2$PRD3/2, v equals 3) + Ne), and the other mediated by interstate transfer (CN(A2$PRD3/2, v equals 3)-Ne yields CN(X, 2(Sigma) +, v equals 7) + Ne). The former was approximately 104 times faster than the latter. Symmetry based propensities were evident in the rotational population distributions of the CN fragments.
