A straightforward numerical approach to estimate the performance of a spatial filter in Raman backscattering spectroscopy has been developed. This approach enabled the authors to determine an optimal hole diameter that balances spatial resolution and signal intensity.

This installment of “Molecular Spectroscopy Workbench” will help readers understand the underlying physics that affect the Raman spectra of crystalline and amorphous solids. Wave vector, reciprocal space, and the Brillouin zone are explained with respect to Raman spectroscopy of solids.

In biomedical applications of surface-enhanced Raman spectroscopy (SERS), nanoparticles can enhance the Raman signal and provide additional functionality. Duncan Graham of the University of Strathclyde has been pushing the limits of what can be achieved using functionalized nanoparticles and SERS, in applications such as cholera detection, lipid profiling in cancer cells, and assessing the efficacy of anti-cancer drugs, For this and other work he has won the 2017 Charles Mann Award, presented by the Federation of Analytical Chemistry and Spectroscopy Societies (FACSS). He recently spoke to Spectroscopy about this work. This interview is part of a series of interviews with the winners of awards that will be presented at the SciX 2017 conference in October.

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.
