Abstract
Using a distributed feedback diode laser, pressure induced self-broadening and shift have been measured for several transitions in the 2 nu(1) + 2 nu(2) + nu(3) band of CO2, centered at 1.573 mu m. Foreign broadening and shift, with N-2 and O-2 as perturbing gas, have been measured for the most intense lines. The results for broadening have been compared with the data given by HITRAN molecular database and some discrepancies have been found, specially for air broadening derived from N-2 and O-2 broadening.
