High resolution spectrum of the N_2^+ Meinel system to 11 250 Å

The Band Spectrum of N2+

“…Bands were eliminated when systematic displacements or misassignments were made apparent by the term value calculations. For example an incompatibility in the (2,3) band of the B-X System was found when testing the data of Dick et al [22] together with the data of Benesch et al [25]. Differences between the observed lines and the reconstructed ones are systematically too large.…”

“…A-X System: The (O,O), (1,0), (2,0), (3,0), (3, 11, (4, 11, (4,2) and (5,2) bands of Benesch et al [25].…”

“…They cover the spectral region from 445 to extended to higher vibrational levels [ 10,111 and entirely new 565 m. many cases the spin doublets were resolved at systems [12-151 of N: were observed. More recently new lower N values than before and the analysis was extended to investigations [16][17][18] or reinvestigations [19][20][21][22][23][24][25][26] have been higher rotational quantum numbers so that new perturbations published. Lofthus' critical summary [271 has been revised by could be observed.…”

Highly excited states of gerade symmetry in molecular nitrogen

“…It is therefore to be expected that the molecular constants of such a series also converge to the constants of the ionic state. In Table IX the constants of the ground state and the first excited state of the molecular ion [45][46][47][48] are listed. Based on the rotational B parameter, a first crude assignment can be made on the character of the excited state.…”
