摘要:

A new low-lying 1Σg+state of the nitrogen molecule was recently predicted from ab initio calculations of the first 102 states which result from nitrogen atoms in the4S,2D and2P states (1). The calculated spectroscopic constants for this new state seemed to fit well with the ones that could be estimated from the unidentified bands at 6895.5 Å and 8937.0 Å reported by Lofthus (2,3). Since spectrograms taken at moderate resolution already were available in the wavelenght region of interest, no new experiments at high resolution were initiated and a search for these bands was made. It was soon found that the wave numbers listed by Lofthus to a certain extent coincided with the listings given by Dieke and Heath (4) for theOP12andOP23satellite branches of the (1, 0) and (3, 0) bands of the B3Σg- A3Σu+transition of N2. No other bands which could be related to the predicted1Σg+state were found in this region.
