Abstract: We studied the hyperfine components of the (J = 10-9, Kl= 9) rotational transition in the nu(6) = 1 excited vibrational state of CH3I, using collinear infrared and mm-wave radiations. The Doppler-free double-resonance technique allowed an accurate determination of the collisional broadening parameters for all the hyperfine components. An evident dependence on the F quantum number was observed and this result is perfectly consistent with a theoretical model allowing calculations of collisional broadening and coupling for the hyperfine components.
