Abstract : Five systems of absorption bands of N2, were investigated in the 1070-1600-A region. A 2-m ad a 3-m vacuum spectrograph, both of normalincidence-type, were used in this work. A final designation of the upper electronic state must come from a rotational analysis, because the observed T00 of the state differed from that of the W state by approximately 40 cm(-1). The potential enejgy curves of the low-lying N2 states prepared by Mulliken are compared with those calculated by using the presently determined constants. (Author)
