THz commensurate echoes: Periodic rephasing of molecular transitions in free-induction decay
(American Physical Society, 1991-04-08)
We report the first study of coherent transients excited by ultrafast pulses of THz radiation. Using a newly developed optoelectronic source of well-collimated beams of subpicosecond pulses of THz radiation to excite N2O ...
Line-shape transition of collision broadened lines
(American Physical Society, 1995-02-20)
Using the newly developed technique of THz time-domain spectroscopy, we have measured the far-wing absorption line profile of the ensemble of collision broadened ground state rotational lines of methylchloride vapor out ...
