Speed Dependence of Pressure Broadening in Molecular Rotational Spectra Using a Novel Technique

Self and Polar Foreign Gas Line Broadening and Frequency Shifting of CH3F: Effect of the Speed Dependence Observed by Millimeter-Wave Coherent Transients

“…other collisional systems involving two polar molecules (35,VI.4. Influence of Velocity Changing Collisions 36), and the same interpretation has been given for experiments at room temperature on the CH 3 I-CH 3 I system (37).…”

The Molecular Constants of12CH3I in the Ground andv6= 1 Excited Vibrational State

“…In this section we report the new measurements obtained in Pisa by the Doppler-splitting method: we use a new version of the IR-millimeter-wave technique (15) to measure the frequency of rotational and vibrational transitions at sub-Doppler resolution. The method employs collinear propagation of pump and probe beams to select a narrow class in the velocity distribution of the molecules.…”

Hyperfine Level Dependence of the Pressure Broadening of CH3I Rotational Transitions in the v6 = 1 Vibrational State

“…The main features of the apparatus have been discussed in Refs. (9,10), and only a short description of recent improvements will be reported here.…”
