HIGH-RESOLUTION LASER-INDUCED FLUORESCENCE SPECTRUM OF THE B-4-SIGMA(-)(U)-X(4)SIGMA(-)(G) TRANSITION OF C-2(+)

摘要

We have used laser-induced fluorescence on a fast ion beam to study the B-4 Sigma(u)(-)-X(4) Sigma(g)(-) system of the homonuclear molecular ion C-2(+). 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. [References: 22]
