Coherent two-dimensional terahertz-terahertz-Raman spectroscopy.
We present 2D terahertz-terahertz-Raman (2D TTR) spectroscopy, the first technique, to our knowledge, to interrogate a liquid with multiple pulses of terahertz (THz) light. This hybrid approach isolates nonlinear signatures in isotropic media, and is sensitive to the coupling and anharmonicity of thermally activated THz modes that play a central role in liquid-phase chemistry. Specifically, by ...
متن کاملNonlinear two-dimensional terahertz photon echo and rotational spectroscopy in the gas phase.
Ultrafast 2D spectroscopy uses correlated multiple light-matter interactions for retrieving dynamic features that may otherwise be hidden under the linear spectrum; its extension to the terahertz regime of the electromagnetic spectrum, where a rich variety of material degrees of freedom reside, remains an experimental challenge. We report a demonstration of ultrafast 2D terahertz spectroscopy o...
متن کاملMicrowave and terahertz spectroscopy
8 1.4.1 Introduction Spectroscopy, or the study of the interaction of light with matter. has become one of the major tools of the natural and physical ciences during this century. As the wavelength of the radiation is varied across the electromagnetic spectrum, characteristic properties of atoms, molecule , liquid and solids are probed. In the optical and ultraviolet regions (A. ""' I J-Lm up t...
متن کاملAnalytical terahertz spectroscopy.
Recent progress in analytical terahertz (THz) spectroscopy is reviewed with illustrative examples showing that it is an effective method for detecting and identifying intermolecular interactions in chemical compounds, such as hydrogen bonds. The unique and characteristic properties of THz waves, their significance to both science and industry, and the bases of one of the successful fields of an...
متن کاملChiral rotational spectroscopy
We introduce chiral rotational spectroscopy, a technique that enables the determination of the orientated optical activity pseudotensor components BXX , BYY , and BZZ of chiral molecules, in a manner that reveals the enantiomeric constitution of a sample and provides an incisive signal even for a racemate. Chiral rotational spectroscopy could find particular use in the analysis of molecules tha...
