Spectroscopy
Controlling the orientation of the laser and Raman polarization relative to the sample orientation can provide a wealth of information. But it is easy to produce erroneous results, so you need to know what instrumental components affect the observed polarization effects and how the sample setup itself affects the Raman signal.

Great care is required when developing Raman spectral libraries for raw material identification. Critical factors—such as instrument type, Raman capability, container type, container interference, background interference, and material variability— can potentially influence the identity of the material.

This technique has the potential to predict α-helix and β-sheet protein structures accurately and to predict other structures with a degree of accuracy previously achieved only with X-ray crystallography. The technique also has many advantages, including quick data acquisition, low sample requirement, and no special processing of raw data other than peak fitting.

Spectroscopy is proud to have created a new award, the Emerging Leader in Molecular Spectroscopy Award. As its name implies, the award recognizes a young scientist, and it is designed to encourage the next generation of molecular spectroscopists. Matthew Baker, the winner of the inaugural Emerging Leader in Molecular Spectroscopy Award, is a senior lecturer in chemistry at the University of Strathclyde, in Glasgow, Scotland. At Strathclyde, Baker leads research to advance the application of analytical chemistry to real-world problems in a variety of areas, including the biomedical, clinical, defense, and security fields. His main focus is the development of spectroscopic and spectrometric molecular pathology, disease diagnosis, and the detection of pathogenic bacteria and toxic chemicals. In particular, Baker has pioneered the use of vibrational spectroscopy for clinical diagnostics.
