✦ Synopsis

Absolute line intensities for the n 9 fundamental ( 458.228 cm 01 ) in HNO 3 were determined for the first time, using tunable diode laser spectroscopy. This technique permitted short integration times, proven important to avoid dissociation in this highly reactive species. Thirty-eight transitions belonging to P and R branches were measured. The absolute value of the transition dipole moment was determined to be 0.2561 ( 21 ) debye, yielding a value for the integrated band intensity at 296ЊK of 209 cm 02 atm 01 . A comparison is made to the previously measured integrated band intensity.

Line intensity measurements have been made on the n 8 band of HNO 3 using a high-resolution Fourier transform infrared spectrum in the region 739-800 cm 01 . A least-squares fit of a total of 710 line intensities in the P and R branches was performed, leading to accurate determination of five dipole

The absolute strengths of 93 lines belonging to the nu2 and nu5 bands of methyl fluoride were measured in the range of 1416-1503 cm-1 using a tunable diode-laser (TDL) spectrometer. These experimental line intensities were obtained from the equivalent width method. The intensities were analyzed with
