Diode-laser measurements of N2-broadening coefficients in the ν10 band of allene at room temperature

Research output: Contribution to journalArticle

Abstract

Using a tunable diode-laser spectrometer, we have measured the N -broadening coefficients of 32 absorption lines in the ν band of allene at room temperature. For each line under study, we have recorded spectra at five pressures of perturber gas ranging from 7 to 37mbar. The line profiles have been fitted, at each pressure, with different lineshape models. From these fits, we have obtained the collisional half-width at each pressure and determined accurately the N -broadening coefficients.
