Question

Calculate the natural mean widths of the bands corresponding to the pure rotational transitions at 10¹¹ Hz, vibrational at 6×10¹³ Hz and electronics at 2×10¹⁵ Hz, characteristic of the CO molecule. The dipole moments of transition are of the order of 1 Debye.

Calculate the average widths due to the Doppler effect for the transitions of the CO molecule at 300 K.

Calculate the average widths due to pressure for the transitions of the CO molecule at 300 K of temperature and 1 atm of pressure. The effective collision diameter is approximately 2 Angstrom.
