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 μm.
Line intensity, self- and foreign broadening and shift, with N2 and
O2 as foreign gases, have been measured with high accuracy in the
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.
