双光子激发NO分子里德伯态H^('2)Ⅱ^-的光谱研究

Spectroscopy of H^2Π-Rydberg states of NO molecular by two-photon excitation

本文采用激光双光子激发的方法对NO分子的里德伯态H^(12)Ⅱ-(v=1,2)进行了研究,得到了该能级的光谱常数;观测到了H^(12)Ⅱ-与非里德伯态B^2Ⅱ之间的相互作用现象,并计算出了相应的转动能级位移;研究了H^(12)Ⅱ-能级的主要荧光跃迁通道。

The Rydberg states H'2II(v = 1, 2) of NO have been studied by two-photon excitation. The molecular constants of the states were obtained. The interactions between Rydberg states H'2II- and non-Rydberg states B2II were observed and the shifts of rotational energy levels were calculated. From the obsarved fluorescence spectra, the main fluorescence transition channels of H'2II- (v =1, 2)were identified.
