The high-resolution spectra of the “hot” 2ν2-ν2 band of the 15NH2D and 15NHD2 molecules were studied for the first time. The analysis is based on the ground state combination differences method. As a result, the energy structure of the inversion-vibrational state (v2 = 2, s) was obtained for both studied molecules; more than 480 vibrational-rotational transitions of the “hot” bands were assign. The values of the upper energy levels determined on the basis of the line positions were used as initial data to determine the spectroscopic parameters of the state (v2 = 2, s).
