Collisional broadening and shift of lines in the 2ν1+2ν2+ν3 band of CO2.
Abstract
Using a distributed feedback diode laser, pressure induced self-broadening and shift have been measured for several transitions in the 2ν1+2ν2+ν3 band of CO2, centered at 1.573 μm. Foreign broadening and shift, with N2 and O2 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, especially for air broadening derived from N2 and O2 broadening.
