LINE-INTENSITIES FOR THE 8-MU-M BANDS OF SO2

Using both high-resolution (R = 0.003 cm(-1)) and medium-resolution (R = 0.12 cm(-1)) Fourier transform spectroscopy, it has been possible t o measure accurately a large set of individual line intensities for th e v(1) and v(3) bands of SO2 in the 950-1400 cm(-1) spectral region. T hese intensities were introduced into a least-squares fit calculation allowing one to obtain the expansion of the transition moment operator of the v(1) and v(3) bands. For these intensity calculations, the the oretical model takes into account the vibration-rotation interactions linking the upper levels involved in the v(1), 2v(2), and v(3) interac ting SO2 bands. Finally, a synthetic spectrum of the 8-mu m SO2 bands has been generated using the dipole moment expansion determined in thi s work and the molecular parameters and the Hamiltonian matrix given i n a previous analysis, (C) 1998 Academic Press.
