Rotational analysis of the NO 2 6125-Å region

Abstract

In the NO 2 6125-Å region 135 transitions belonging to four bands have been assigned using laser-induced fluorescence. On the whole, the rotational structure of the four vibronic bands is well characterized by near-prolate symmetric top relations. The 6125 and 6126-Å bands perturb each other, the former having predominantly the character of the A ̃ 2B 2 state, the latter the X ̃ 2A 1 state; this parent-daughter relationship is recognized to occur else-where in the NO 2 visible spectrum.
