He, Ar and N2 broadening coefficients for the V4band of CF4

Broadening coefficients for the ν 4 fundamental band of carbon tertafluoromethane, CF 4 , have been measured for the systems with argon, helium and nitrogen. Broadening coefficient behavior is similar to that previously reported for linear molecules: they coincide for P and R branches; the m-dependence in case of argon is sharper than that for helium. The broadening for nitrogen and helium are practically the same but the values for nitrogen are scattered around the general tendency. O-branch broadening is also discussed. Our experimental data permitted us to evaluate the line intensity distribution and integrated intensity of the band.
