The N-broadening coefficients of ethane for 15 lines in the ν band at five pressures of nitrogen were measured. The measurements were carried out with a 1-m base White-type cell adjusted for four transits, yielding an optical path of 4.17 m. The average values of the N-broadening coefficients obtained at 296 K from the Voigt and Rautian line shapes are respectively equal to 0.0822 and 0.0864 cm atm. The results derived from the Voigt profile are 2 10% lower than those derived from the Rautian model. No rotational dependence is observed over the limited range of rotational quantum numbers investigated. The results also show that the adjustment of the Rautian profile provides an additional parameter, the collisional narrowing coefficient β.
