Br2分子里德堡态的高分辨转动谱研究
Study on the Rotational Structure of Br2Rydberg States Using High Resolution Laser Spectroscopy
摘要
用窄线宽(0.08ｃｍ-1)脉冲可调谐紫外激光和(2+1)多光子电离方法测量了Br2的里德堡(Rydberg)态光谱，在70000～71500 cm-1范围内，获得了溴分子[Π3/2]4d振动系列，测量(ｖ′，ｖ”)＝(1，0)，(2，0)的高分辨振转谱，得到其转动常数B′79-81分别为0.08832和0.08805 cm-1.并提出此系列的角动量量子数Ω应为1.
Abstract
The Rydberg state spectra of Br2 were measured by the method of (2+1) multiphoton ionization with a pulsed, tunable and narrow linewidth (0.08 cm-1) UVlaser. The 4d vibrational series has been obtained in the region of 70000-71500 cm-1. The high resolution vibronic spectra of (v',v")=(1,0),(2,0) have been measured. Their rotational constants B'79,81 are 0.08832 and 0.08805 cm-1 respectively. The angular momemtum Q is suggested to be 1.
