Notizen:
Line mixing effects have been observed in absorption spectra recorded, at room temperature, with a Fourier spectrometer. They concern the Q branches of the ν1+ν2 band of N2O, centered at 1880.2 cm−1 and of the (1110)I←(0220) band of CO2, centered at 740.8 cm−1. For the N2O spectra, the gas was pure and its pressure has been raised up to more than 6 atm. The CO2 spectra were registered with a total gas pressure below 1 atm and the gas was either pure or mixed with argon or nitrogen. Comparison is made between the experimental results and computations taking into account the off-diagonal elements of the relaxation matrix.
