title: New band systems of SiN radical.
abstract: Emission spectra of SiN radical are recorded in the region of 505-720 nm using laser ablation technique and the total 62 bands are observed. Out of total 62 bands, 44 bands are observed for the first time while the rest 18 bands are reported by earlier workers. The total 53 bands are analyzed into two new quartret-quartret band systems f(4)Σ(-)-d(4)Σ(-), g(4)Π-d(4)Σ(-) while the rest nine bands are analyzed into previously reported B(2)Σ(+)-X(2)Σ(+) system. The vibrational constants of these states are determined and reported.
