Simultaneous Neutron Scattering and Raman Scattering
Applied Spectroscopy, 2009The capability to make simultaneous neutron and Raman scattering measurements at temperatures between 1.5 and 450 K has been developed. The samples to be investigated are attached to one end of a custom-made center-stick suitable for insertion into a 100 mm-bore cryostat.

This paper briefly reviews some aspects of electronic Raman scattering in simple semiconductors. Emphasis is placed on the strength of the scattering as predicted by the f-sum rule. The mechanism for light scattering by free and bound electrons in a many-valley semiconductor is outlined.

This chapter describes the application of stimulated Raman scattering as a practical method for the generation of tunable, coherent radiation. A brief theoretical discussion of the stimulated Raman effect in the steady state and transient-scattering regimes is presented.

Abstract It is difficult to provide an overview from the physical standpoint of the enormous number of Raman scattering studies performed under pressure. On the other hand, the experimental aspect seems too simple: only a slight modification of the optical scheme is needed to replace a sample by a high-pressure cell, especially by a ...

Instantaneous integrated Raman scattering
Applied Optics, 1983Lidar detection of atmospheric molecules using a Raman scattering technique being usually limited by low signals is enhanced by integration of the forward Raman scattered light over a large atmospheric volume. This integral can be measured instantaneously in the presence of a reflector at one edge of the optical path, increasing the SNR by a factor of ...

Quadrupole-Enhanced Raman Scattering
ACS Nano, 2014Dark, nonradiating plasmonic modes are important in the Raman enhancement efficiency of nanostructures. However, it is challenging to engineer such hotspots with predictable enhancement efficiency through synthesis routes. Here, we demonstrate that spiky nanoshells have designable quadrupole resonances that efficiently enhance Raman scattering with ...

Tip-enhanced Raman scattering (TERS) is a technique that provides molecular information on the nanometre scale. Using a nanometre-sized metal particle results in a strong signal enhancement and a lateral resolution similar to the dimensions of the particle.

Science, 1972
Laser Raman scattering data for nitrogen, oxygen, and water vapor have been obtained from hydrogen-air and hydrogen-oxygen flames. The resulting ground-state and upper-state vibrational bands exhibit strong asymmetrical broadening. Experimental spectral profiles have been fitted theoretically to give a new measurement technique for the determination of

Hole-Enhanced Raman Scattering
Applied Spectroscopy, 2006Stokes and anti-Stokes non-resonant hole-enhanced Raman scattering (HERS) spectra with high signal-to-noise ratio (S/N) are reported for the first time for aqueous phase R6G molecules adsorbed onto random nanoholes in thin gold films. Compared to conventional surface-enhanced Raman scattering from nanometric gold colloid particles, HERS exhibits ...

Enhanced Raman forward scattering
Physical Review E, 1996Recent experiments on laser wake-field acceleration have indicated a dramatically enhanced value of the accelerating field created through the process of the Raman forward scattering instability. However, the use of the Raman forward scattering instability can be improved.
