Microwave 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 کاملIv. Microwave Spectroscopy
The side-arm method for observing chemical recombinations described in the Quarterly Progress Report of April 15, 1958, page 24, is being used to study oxygen-atom recombination within the gas volume and on surfaces. Two modes of volume recombination have been considered: (a) O + 0O3 +0 203 0 03 + O 02 + 02 (b) O + O + 0 2 O + O 2 Reaction (a), involving ozone as an intermediate, proceeds at a ...
متن کاملPulsed Microwave Microwave Double Resonance Spectroscopy with Fourier Transform Technique
Recently we showed that microwave (MW) double resonance experiments can be performed with microwave Fourier transform (MWFT) techniques [1]. In our first experiments we used a continuous microwave (CW) pump radiation. One observation is that the transient emission signal in the presence of a CW p u m p radiation decays faster. This results in an additional line broadening, as can be seen in Fig...
متن کاملMicrowave spectroscopy of biomolecular building blocks.
Microwave spectroscopy, considered as the most definitive gas phase structural probe, is able to distinguish between different conformational structures of a molecule, because they have unique spectroscopic constants and give rise to distinct individual rotational spectra.Previously, application of this technique was limited to molecular specimens possessing appreciable vapor pressures, thus di...
متن کاملMicrowave Spectroscopy at the Dissociation Limit
An ion beam technique has been developed that combines some of the methods of mass spectrometry and molecular spectroscopy and is designed for the study of molecular ions at energy levels lying very close to the lowest dissociation limit. Microwave radiation is used to drive spectroscopic transitions, and electric field dissociation of the weakly bound levels provides a high degree of state sel...
