表面增强拉曼 SERS(Surface-Enhanced Raman Scattering)???表面增强拉曼是用通常的拉曼光谱法测定吸附在胶质金属颗粒如银、金或铜表面的样品,或吸附在这些金属片的粗糙表面上的样品。尽管原因尚不明朗,人们发现被吸附的样品其拉曼光谱的强度可提高103-106倍。如果将表面增强拉曼与共振拉曼结合,光谱强度的净增加几乎是两...

Coherent anti-Stokes Raman scattering: from proof-of-the-principle experiments to femtosecond CARS and higher order wave-mixing generalizations A. M. Zheltikov* Article first published online: 13 SEP 2000 DOI: 10.1002/1097-4555(200008/09)31:8/9<653::AID-JRS597>3.0.CO;2-W Copyright ©...
Other optical pumping techniques for preparing vibrationally excited molecules include Franck–Condon Pumping (FCP) and stimulated Raman scattering with adiabatic passage (STIRAP). FCP provides a means for producing and controlling vibrationally excited population distributions. FCP was first applied to ...
We present a first-principles density-functional calculation for the Raman spectra of a neutral BEDT-TTF molecule. Our results are in excellent agreement with experimental results. We show that a planar structure is not a stable state of a neutral BEDT-TTF molecule. We consider three possible co...
Raman lasers utilize amplification based on stimulated Raman scattering. Light from such devices can have laser-like properties, such as strongly directional emission, high spatial and temporal coherence and a narrow optical bandwidth. In other cases, the term laser sources is justified by the fact ...
