Reinvestigation of Emission Spectra of Silicon Dimer in 360-540 nm Region

Abstract

The emission spectra of silicon dimer were reinvestigated in the region of 360-540 nm using laser ablation technique. About 100
bands were observed in this region and all these bands were classified into three transitions. Out of these three transitions, two transitions in 454-538 nm and 360-415 nm regions were new while the third transition, in 362-470 nm region, had been previously reported as H-X transition. The molecular constants of all these three transitions were determined and reported
