Oxygen-broadening coefficients have been measured for nitric oxide lines in
the first overtone band. No direct measurement is possible because of the
quick decomposition of NO in the presence of O-2. A general method has been
set up to obtain collisional widths from FT spectra when the experimental
conditions, inside the absorption cell, have varied during the recording of
the interferogram. This procedure was applied to the determination of the
NO collisional widths in the presence of O-2. (C) 1999 Elsevier Science Ltd
