dc.description.abstractIn previous work we have recorded and analyzed three bands of Ne-CN which were associated with the CN B-X 0-0 transition. These features were assigned to the electronic origin and two internal rotor levels [Y. Lin and M. C. Heaven, J. Chen. Phys. 94, 5765(1991)]. More recently we have re-examined the $Ne-CN$ $B-X$ spectrum in the vicinity of the CN 0-0 transition, and recorded spectra for the bands associated with the CN 1-0 transition. Ten previously unobserved bands have been characterized. Features corresponding to multiple excitations of the internal rotor mode, and excitation of the CN-Ne stretch, are present. We are in the process of fitting a two-dimensional potential energy surface to this date. A search for Ne-CN bands associated with the CN $A-X$ 3-0 transition was made. A single feature, with a homogenously broadened national envelope, was observed next to the CN $A^{2}\Pi_{1/2}-X$, 3-0, R(1) line. Complex features associated with the $A^{2}\Pi_{3/2}-X$ transition could not be found. A possible explanation for these results in that $Ne-CN(A, v=3)$ is subject to rapid predissociations caused by spin-orbit relaxation and internal conversion. The fact that fluorescence cannot be seen following excitation of the lower energy spin-orbit component suggests that internal conversion $(Ne-CN (A^{2}\Pi_{3/2}, v=3) \rightarrow Ne + CN X)$ is much faster that A state radiative decay. Observation of fluorescence following excitation of the higher energy spin-orbit component would then imply that spin-orbit relaxation $(Ne-CN(A^{2}\Pi_{1/2}, v=3). Ne \rightarrow Ne + CN A^{2}\Pi_{3/2}, v=3$) is much faster that internal conversion. These speculations are being explored in a series of opticalûoptical double resonance experiments.en_US
