Molecular rotational resonance (MRR) spectroscopy gives spectral signatures with high chemical selectivity. At room-temperature, the peak intensity of the MRR spectrum occurs in the 100 GHz – 1 THz frequency range. Advances in high-power sub-mm-wave light sources has made it possible to implement time-domain Fourier transform (FT) spectroscopy techniques that offer speed and sensitivity enhancments over direct absorption methods. For chemical analysis, FT-MRR spectrometers combine the benefits of broad chemical coverage typical of gas chromatography – mass spectrometry (GC-MS) instruments and the direct measurement capabilities of infrared gas sensors all in a reprogrammable platform.

Photonics West is hosted by SPIE, the international society for optics and photonics. More information is available here. {link to: //
