title: Experimental determination of a spin-orbit interval in the C" 5Pi(ui) state of 14N2.
abstract: We have developed an experimental setup using the combination of laser optogalvanic detection and a supersonic expansion of excited N2 to record the high resolution spectrum of the (3-1) and (4-2) Herman infrared bands (C" 5Pi(ui)-A' 5Sigma(g)+). We report the first experimental determination of a spin-orbit interval (about 24 cm(-1)) in the C" 5Pi(ui) state of N2 for both the (3-1) and (4-2) vibrational bands as well as the first observation of the v' = 4 vibrational level.
