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

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 ...

Definition:Raman Spectroscopy is a sophisticated analytical technique used to observe vibrational, rotational, and other low-frequency modes in a system. This material characterization technique ...

Laser lights are usually employed for the Raman spectroscopic analysis. The photons emitted by the laser light are absorbed by the sample, temporarily entering a non-stationary, exceedingly brief ...
