Abstract
A new 3Î -3Σ band was observed in a discharge plasma of the nitrogen molecule and helium using near-infrared diode laser kinetic spectroscopy. All the lines in this band exhibited line broadening of more than 0.1 cmâ1. Rotational analysis revealed that the lower state of the transition was the E3Σg+(v=0) state of N2, which had already been studied in the D3Σ-E3Σ band. The term value and rotational constant suggested that the upper state is the G3Î u Rydberg state with an electron configuration of (N2+:X2Σ core)(3pÏu). The line broadening is attributed to predissociation through a homogeneous interaction with a repulsive Î u state.
