Abstract.
Fundamental spectroscopical parameters of the weak ν1+3ν2 1-ν2 1+ν3 band of CO2 are reported using a high-resolution, direct-absorption spectrometer, based on a distributed feed-back diode laser emitting at 2 μm. Line intensities and self-broadening coefficients have been measured for the first time with high accuracy, for nine lines of the R branch, from R(44) up to R(59). Comparison with available data has been made, and a generally good agreement has been found.
