High-resolution measurements of line intensity, broadening and shift of CO2 around 2 mu m

Fundamental spectroscopical parameters of CO2 are reported using a high res olution, direct absorption spectrometer, based on a distributed feed-back d iode laser emitting at 2 mu m. Line intensity, self and foreign broadening and shift, with Na and O-2 as foreign gases, have been measured with high a ccuracy in the vl + 2v(2)(0), +/- vs 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.
