Abstract:
The laser-induced fluorescence excitation spectrum of jet-cooled NiS molecule has been recorded in the energy range of 15500-17200 cm-1. Fifteen bands have been assigned as three transition progressions: [15.65]3Π1(v′=0-4)-X30- (v"=0), [15.69]3Π1(v′=0-4)-X30-(v"=0). Spectroscopic constants for the three newly identified electronically excited states have been determined for the first time. In addition, the lifetimes for most observed vibronic bands have also been measured.

摘要:
测量了在15500~17200 cm-1的超声射流冷却的NiS自由基的激光诱导荧光激发谱. 15条谱带被归属为三个电子态激发态分别为:[15.65](v′=0~4)~X(v"=0),[15.69](v′=0~4)~X(v"=0),和[15.81](v′=0~4)~X(v"=0). 三个新发现的电子激发态的光谱常数为首次确定. 此外,大多数观察的振动带的寿命也得到了测量.
