摘要：

Using a tunable diode-laser spectrometer, we have measured the N-2-broadening coefficients of allene for 5 lines in the nu(10) fundamental band near 11 mu m at five low temperatures ranging from 167.7 K to 259.7 K. The collisional halfwidths have been obtained by fitting the spectral lineshapes with the Voigt and the Rautian profiles. For these lines, the is parameter of the temperature dependence has been determined giving respectively mean values of 0.651 (0.038) and 0.612 (0.027) for the Voigt and Rautian models.
