Abstract
The authors report on the room-temperature characterization of a narrow absorption signature in an organic molecular solid ( α -lactose monohydrate) centered around 530 GHz and having a full width at half maximum as small as 23 GHz . Three different spectrometric techniques were applied, two of them (tunable photomixing and tunable frequency multiplication) having a high enough resolution ( ⪡ 100 MHz ) to accurately curve fit the signature and determine that it is much better described by a Lorentzian than a Gaussian function. The Lorentzian model provides an estimate of 14 ps for the damping time associated with this signature.
