Abstract
The rotational analysis of the n+4, 3 band of the ``Y'' system of N2 shows that the initial state is a 3Σu— level with Bn+4 = 1.3325. The band has exactly the structure to be expected from a 3Σu—→3IIg transition and all expected 27 branches have been observed. The triplet separation of the 3Σ state degenerates into a doublet for all but the lowest values of K as the two states with J = K±1 nearly coincide.Keywords
