title: Near-Infrared Diode Laser Spectroscopy of the Nitrogen Molecule in Rydberg State: Analysis of the c1Piu - a"1Sigmag+, v = 1-0 Band
abstract: 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
