Super resolution of A 400 MHz rotational line doublet with a TDS using a 850 ps long delay line

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 NH 3 doublet separated by ~400MHz in experimental data despite the 1.2 GHz delay line limitation.
