✦ Synopsis

The (\nu_{4}) fundamental ( (\mathrm{OH}) torsion) bands of hydroxylamine (\mathrm{NH}{2} \mathrm{OH}) have been observed for the first time at high resolution in the (385 \mathrm{~cm}^{-1}) region, by Fourier transform infrared spectroscopy. About 5000 lines belonging to (\nu{9}) and the two hot bands (2 \nu_{9}-\nu_{9}) and (3 \nu-2 \nu_{9}) have been measured with an accuracy of about (0.001 \mathrm{~cm}^{-1}). Molecular parameters have been derived with a Watson (S)-reduced asymmetric-top Hamiltonian. The band origin frequencies have been determined to be (\nu_{1-0}=385.96331(8) \mathrm{cm}^{-1}, \nu_{2-1}=365.11220(14) \mathrm{cm}^{-1}), and (\nu_{3-2}=345.84124) (22) (\mathrm{cm}^{-1}). The splittings due to the inversion of the (\mathrm{NH}_{2}) group are not resolved in the observed spectrum. 1995 Acudemic Press, Ine

The visible spectrum of NiCl consists of a large number of bands. Laser-induced fluorescence experiments have shown that two intense transitions (21 910 and 21 750 cm Ϫ1 ) share a common [21.9] 2 ⌬ 5/2 upper electronic state. High-resolution Fourier transform spectroscopy has allowed the rotational
