Resonance hyper Raman spectroscopy, on the other hand, can excite atoms to emit light at wavelengths outside the laser’s tunable range, thus expanding the range of possible components of a molecule that can be excited and therefore studied. Resonance hyper Raman spectroscopy is one of the types of “non-linear” Raman spectroscopy.
Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint by which molecules can be identified. published in March 1928 by Raman & Krishnan.[2] Almost simultaneously, soviet physicists Landsberg & Mandelstam observed the same effect in crystals.[3] The phenomenon was named after the Indian physicist Chandrasekhara Venkata Raman, who was awarded The Nobel Prize in Glass of the Na2O – B2O3 – SiO2 system with a B2O3 content from 20 to 40% was investigated by high-temperature Raman spectroscopy.
Resonance Raman spectroscopy (RR spectroscopy) is a Raman spectroscopy technique in which the incident photon energy is close in energy to an electronic transition of a compound or material under examination. The frequency coincidence (or resonance) can lead to greatly enhanced intensity of the Raman scattering, which facilitates the study of chemical compounds present at low concentrations.

The scattered light can be detected by a Raman spectrometer and represents a “chemical fingerprint” of the substance.
We present a high-throughput screening Raman spectroscopy (HTS-RS) platform for a rapid and label-free macromolecular fingerprinting of tens of thousands eukaryotic cells. The newly proposed label-free HTS-RS platform combines automated imaging microscopy with Raman spectroscopy to enable a rapid label-free screening of cells and can be applied to a large number of biomedical and clinical
An ultrasonic standing wave field of 2MHz was used to manipulate yeast cells and theophylline crystals in suspension to control the local concentration of solid material in the focus of a Raman spectroscope to improve the signal quality of such measurements for suspensions. In case of agglomerated yeast cells the signal-to-noise ratio was significantly increased in comparison to Raman spectra

As an example, it is accepted that glass has a relatively weak Raman spectrum. However, the spectrum of glass can be made to appear strong by doing multiple scans (Figure 1). Poly(methyl methacrylate) (PMMA) is a very versatile polymer which is used as a glass substitute or as an economical alternative to polycarbonate for many types of important applications, due to its particular physical properties. In this study we deal with the Raman spectroscopic characterization of the gla Glass 01 Raman analysis of laser-processed glass materials Laser processing provides a fast, non-contact and flexible method of modifying and patterning materials, from glasses to metals.
