The temperature dependence of the pressure-broadening parameters of the J = 1 ⇐ 0 rotational transition of OCS and H_{2} in the ground vibrational state of CH_{3}C_{14}N molecule is measured in the temperature range between 248 and 293 K. The line shape of the absorption is recorded with a Stark modulated microwave spectrometer. Using least squares fits of the data to the Voigt line function, several contributions to the linewidth have been de­duced. The experimental results are compared with the calculated results us­ing Murphy and Boggs collision broadening theory. The pressure-broadening parameters C_{W}(x) of the gas mixture CH_{3}CN+OCS and CH_{3}CN+H_{2} are 14.05±0.30 MHz/Tr, 9.15±0.12 MHz/Tr, respectively and the temperature dependence parameters α are -0.90 ± 0.07 and -0.77 ± 0.08.
