Résumé

Using a tunable diode-laser spectrometer, we have measured the N2-broadening coefficients of allene for 5 lines in the ν10 fundamental band near 11 μm 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 n 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.
