Fundamental spectroscopical parameters of CO2 are reported using a high resolution, direct absorption spectrometer, based on a distributed feed-back diode laser emitting at 2 micron. Line intensity, self- and foreign broadening and shift, with N2 and O2 as foreign gases, have been measured with high accuracy in the nu1 + 2nu02 + nu3 combination band of CO2, for 13 lines of the R branch, from R(22) up to R(46). Comparison with available data is made, when possible, and a generally good agreement has been found.

Abstract
Fundamental spectroscopical parameters of CO2 are reported using a high resolution, direct absorption spectrometer, based on a distributed feed-back diode laser emitting at 2 micron. Line intensity, self- and foreign broadening and shift, with N2 and O2 as foreign gases, have been measured with high accuracy in the nu1 + 2nu02 + nu3 combination band of CO2, for 13 lines of the R branch, from R(22) up to R(46). Comparison with available data is made, when possible, and a generally good agreement has been found.File in questo prodotto:
