Abstract:
The magnitudes of half-width and shift of NO2 absorption lines of nu3 band induced by noble gases pressure have been measured using a diode-laser spectrometer with 3 10-4 nm-1 resolution. The magnitudes of mean polarizability of NO2 molecule in 001 vibrational state and z-components of the polarizability tensor in 000 and 001 states were determined from the measured shift coefficients for NO2 - Ar, NO2 - Kr, and NO2 - Xe mixtures. The data obtained were used in calculation of NO2 absorption line half-widths. The calculation results well agree with the experimental data.
