Paper Abstract

Self-, CO2-, N2-broadened line widths of NO2 molecule have been obtained at the room temperature for ~400 000 lines, rotational quantum numbers vary in the range: J to 70 и Ka to 20. The temperature exponents for every line were calculated. The data have been evaluated theoretically in the frame of two methods: semi-empirical approach based on analytical expressions and including a few-parameter correction to account for the real curved trajectories and averaged energy differences method. Being validated by comparison with measurements, these approaches were used to compute extensive line list which could be useful for atmospheric, astrophysical applications and spectroscopic databases.
