A new singlet-singlet absorption band between Rydberg states of the nitrogen molecule was studied by near-infrared diode laser spectroscopy in the 1.3 &mgr;m region. An analysis was made for the band to establish line assignments and determine molecular parameters for both the lower and the upper vibronic states. As a result of the analysis, this band was assigned to the c1Piu-a"1Sigmag+, v = 1-0 band. The anomaly of the Lambda-type doubling structure in the c1Piu (v = 1) state was discussed in connection with the interaction with the b'1Sigmau+ (v = 4) state. The predissociation in the c1Piu (v = 1) state was also discussed relating with the line broadening observed. Copyright 1997 Academic Press. Copyright 1997Academic Press
利用近红外二极管激光光谱技术,在1.3微米区域对氮分子里德堡态之间的一个新的单重态 - 单重态吸收带进行了研究。对该吸收带进行了分析,以确定谱线归属,并确定上下振转态的分子参数。分析结果表明,该吸收带被归属为c1Piu - a"1Sigmag +,v = 1 - 0带。结合与b'1Sigmau +(v = 4)态的相互作用,讨论了c1Piu(v = 1)态中Lambda型双重结构的异常现象。还结合所观察到的谱线展宽,讨论了c1Piu(v = 1)态中的预解离现象。版权所有1997年学术出版社。版权所有1997年学术出版社
