Article Description

Several previously unmeasured transitions of 12 CH 3 D have been recorded by a terahertz photomixing continuous-wave spectrometer up to Q R (10) branch at 2.5 THz. An improved set of rotational constants has been obtained utilizing a THz frequency metrology based on a frequency comb that achieved an averaged frequency position better than 150 kHz on more than fifty ground-state transitions. A detailed analysis of the measured line intensities was undertaken using the multispectrum fitting program and has resulted in a determination of new dipole moment parameters. Measurements at different pressures of the Q R (7) transitions provide the first determination of self-broadening coefficients from pure rotational CH 3 D lines. The THz rotational measurements are consistent with IR rovibrational data but no significant vibrational dependence of self-broadening coefficient may be observed by comparison.
