Fundamental spectroscopical parameters of CO2are reported using a high resolution, direct absorption spectrometer, based on a distributed feed-back diode laser emitting at 2 μm. Line intensity, self- and foreign broadening and shift, with N2and O2as foreign gases, have been measured with high accuracy in the ν1+ 2ν02+ ν3combination 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.
