Self- and foreign-broadening and shift coefficients for C2H2 lines at 1.54 micron

In this article we present experimental data for line parameters measurements of several transition lines of overtone bands of C2H2 at 1540 nm. The measurements were done with a spectrometer based on a semiconductor diode laser and a direct absorption spectroscopy scheme. Broadening and shift coecients have been measured for the pure gas or in mixtures with N2, O2 and CO2 as perturbing gas.
