Temperature dependence of self-broadening of allene in the ν10 band

Research output: Contribution to journalArticle


Using a tunable diode-laser spectrometer, we have measured self-broadening coefficients of allene for 4 lines in the ν10 fundamental band near 11 μm for three low temperatures (178.15, 208.15, and 243.65 K). The collisional halfwidths are obtained by fitting the spectral lines with a Voigt and a Rautian profile. For these lines, the n parameter of the temperature dependence has been determined giving a mean value of 0.700. © 2014 Published by Elsevier Inc.
