The strength of a Raman signal is inversely proportional to the fourth power of the wavelength of the scattered light. In practical terms, this means that the longer the excitation wavelength used to ...

While Raman spectroscopy has been hugely successful in a number of domains of chemistry and materials science, 1-3 one of the main challenges with performing Raman measurements is the inherently weak ...

Active pharmaceutical ingredients (APIs) are typically produced through crystallization. In this process, an organic molecule can take on multiple crystalline forms. Solid-state characteristics, ...

Yet, that does not get to the core of the actual difference between these two methods, and why SERS (surface-enhanced Raman scattering, or alternatively surface-enhanced Raman spectroscopy) is often ...
