H 2 -broadening coefficients have been measured for 29 lines of C 2 H 2 at 173.2 K in the P and R branches of the ν 5 fundamental band near 13.7 µm, using a tunable diode-laser spectrometer. These lines were individually fitted with a Voigt and a Rautian profile in order to determine the collisional

The nitrogen and oxygen broadening coefficients of ozone have been experimentally obtained at two low temperatures (227 and 186 K) in the n 1 / n 3 band, located at 2110 cm 01 . Thirty-five transitions have been chosen to derive the n coefficient defined by a(T ) Å a(T o )r(T o /T ) n . This is foun
Ar-broadening coefficients have been measured in the P-and R-branches of the m 5 fundamental band of C 2 H 2 for 30 lines at room temperature and 8 lines at )100 °C, using a tunable diode-laser spectrometer. These lines with J values ranging from 2 to 27 are located in the spectral range 665-795 cm
