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

✦ Synopsis
We have used laser-induced fluorescence on a fast ion beam to study the B 4~-_X 4~g system of the homonuclear molecular ion C~-. We have observed rotational lines of the (1, 1) band by using a Doppler tuning technique and the high resolution obtained has permitted a detailed study of spin splitting. Molecular constants and interaction parameters were evaluated including revised results for the (1, 0) band.

High-resolution laser excitation spectra have been obtained for the 0-0, 1-1, and 0-1 bands of the B 2 + -X 2 + transition of YbCl and a rotational analysis has been performed on the 174 Yb 35 Cl and 172 Yb 35 Cl isotopomers. Comparison of the spin-rotation constant, γ , for the B 2 + state with the
