We conducted broadband absorption measurements of atmospheric water vapor in the ground
state, X 1A1 (000), from 0.4 to 2.7 THz with a pressure broadening-limited resolution of 6.2
GHz using pulsed, terahertz time-domain spectroscopy (THz-TDS). We measured a total of
seventy-two absorption lines and forty-nine lines were identified as H2160 resonances. All
the H2160 lines identified were confirmed by comparing their center frequencies to
experimental values available in the literature.
Here’s what’s next.
