| Abstract | The absorption spectrum of NH 2 has been recorded continuously between 3500 and 2900 cm with a difference frequency laser spectrometer along with the velocity modulation technique. The molecular ions were produced in the positive column of an ac glow discharge with a gas mixture of N2/H2/He in a ratio of around 1/1/100 with a total pressure of Ç7 Torr. In view of the very low barrier to linearity (155 cm) and the high bending vibrational states involved, the observed spectrum was analyzed using the Hamiltonian for linear molecules. The choice of this model is discussed in relation to the previous experimental results and ab initio calculations. Four hot bands have been assigned: 2n2 / n3 R 2n 2, n1 / n3 R n1, n1 / n2 / n3 R n1 / n2, and 2n1 / n3 R 2n1. The matrix elements of the Hamiltonian used for the analysis of the rotational fine structure of the excited degenerate bending vibrational states of a linear molecule in a triplet electronic state are presented. The resultant rotational and vibrational constants are discussed. q 1996 Academic Press, Inc. |
