✦ Synopsis

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.

The dependence of the electronic transition moment, Re(R), of the A10(B 2X+-X 2E+) system on the internuclear distance, R, has been determined by an analysis of the intensity distribution of the emission spectra as Re(R)= [1 -2.29(13XR/,~-1.5) 2] (1.510 A ~<R ~< 1.836 ,~).
