The detailed analysis of the Ã2A1-X̃2B1 spectrum of NH2 in the region 5300 to 6800 Å is reported. Term values derived from the analysis are also presented. Numerous new vibronic substates have been identified. The assignment of the substates and the perturbations detected are discussed in detail, making reference to the calculations of Jungen, Hallin, and Merer and also drawing on the argon matrix absorption spectrum of Robinson and McCarty. The parameters of a simplified model Hamiltonian are reported for most of the substates. The comparison of these results to the calculations of Jungen, Hallin, and Merer, along with the tendencies in the behavior of the spin-orbit coupling constant detected in their work, facilitated the assignments in the present work.
