Self- and foreign-broadening and shift coefficients for C

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 coefficients have been measured for the pure gas or in mixtures with N2, O2 and CO2 as perturbing gas
