✦ Synopsis

Foreign gas effects were measured for the rovibrational lines of (\mathrm{NH}{3}) in the (\nu{2}) band with (\mathrm{O}{2}), (\mathrm{N}{2}), and air as perturbers, using a high-resolution FTIR spectrometer. The observed line profiles were analyzed by the Voigt-type line profile function, and the Lorentzian broadening coefficients have been determined precisely for 176 lines. The observed air broadenings were in very good agreement with the concentration-weighted average of the (\mathrm{N}{2}) - and (\mathrm{O}{2})-broadening coefficients. c) 1995 Academic Press, Inc.
