What is An analysis of the B 2Σ+ − X 2Σ+ emission of SiN. Dependence of the electronic transition moment on the SiN internuclear distance about?

The relative intensity of the SiN( B \*x\*-X \*Z') emission spectrum was analyzed. The relative value of the electronic transition moment, k(R), was found to depend linearly on the internuclear distance, R, as k(R) = I -0.493( 12) (R/A) (l.O55<R6 1.835 A). The validity of the r-centroid approximation is discussed on the basis of the Rydberg-Klein-Rees potentials of the B \*I;+ and X \*Z+ states of SIN. This strong A dependence, which is similar to that observed for the isovalent CN( B \*F-X 'Z+) transition, indicates a strong R dependence of the configuration mixing in the B %+ state of SIN.
