N2О-broadening coefficients of CO2 lines and their temperature exponents were calculated for a wide range of rotational quantum number in the 0001-1000 band. We used the semi-empirical method based on the semi-classical impact theory. It has been already applied for calculation of pressure broadening and shifting coefficients of spectral lines and their temperature exponents for Н2О-N2(О2), СО2-N2(О2), and О3-N2(О2) systems. The computed collisional half-widths were compared with the measured data obtained using a frequency-stabilized tunable СО2-laser for 11 rovibrational transitions with lower state rotational quantum number up to 38 at room temperature and for 3 transitions R(10), R(22), R(32) in temperature range 300ЈТЈ700°K in the 0001-1000 band. The calculated and measured data are in a good agreement.
