✦ Synopsis

Stimulated emission pumping (SEP) spectroscopy was used to characterize vibrationally excited levels (u= 4-6) of the X ?8; ground electronic state of Cc. Rotationally resolved B 42; +??Zg transitions were detected by observation of a decrease in the total laser-excited fluorescence (LEF) signal from the B 'E; (v' = 2) level. In order to obtain the SEP spectra, a modulation scheme which discriminated against one-photon fluorescence signals was successfully employed. The SEP line positions were used together with those from a previous LEF study to improve the molecular constants of the jz %g state of CT.

The velocity modulation laser absorption technique was employed to obtain the spectrum of the \((0,1)\) band of the \(B^{4} \Sigma_{u}^{-}-X^{4} \Sigma_{g}^{-}\)system of \(C_{2}^{+}\). These states were rotationally analyzed and a study of the \(B^{4} \Sigma_{u}^{-}-2^{2} \Pi_{u}\) interaction was
