Super resolution of a 400 MHz rotational line doublet with a TDS using a 850 ps long delay line
Abstract
We improved the spectral resolution of THz time domain spectroscopy beyond the limit given by the delay line length. The constraint reconstruction algorithm used successfully depicted the 1.21 THz NH3doublet separated by ~400MHz in experimental data despite the 1.2 GHz delay line limitation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
