Coherent Terahertz Hyper‐Raman Spectroscopy

Journal of Raman Spectroscopy
ABSTRACTIn this paper, we review our recent discovery of a novel nonlinear effect in the terahertz frequency range, which we have termed terahertz hyper‐Raman (THYR) spectroscopy. This technique shares many characteristics with conventional hyper‐Raman spectroscopy but is applied within the THz spectrum.

Terahertz Desorption Emission Spectroscopy [PDF]

, 2019
Enhancing our understanding of the formation and evolution of the Universe is strongly dependent upon the observation of matter that exists between the stars and that forms the interstellar medium (ISM). Using Radio-telescopes based on heterodyne detection (such as ALMA), nearly 200 molecules have been detected. Whilst molecules, such as H2O and CH3OH,
