Fundamental spectroscopical parameters of the weak v1 + 3v21 - v21 + v3 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. © Springer-Verlag 2000.
