Raman spectroscopy is a spectroscopic technique used to observe vibrational, rotational, and other low-frequency modes within a sample. Raman spectroscopy is commonly used to identify and quantitate the molecules within a chemical sample. The technique involves shining a laser on a sample and detecting and analyzing the scattered light. The advantages to this type of spectroscopy are its high chemical specificity, sampling versatility, relatively low maintenance, minimal sample preparation, fast and simple routine analysis, and the ability to transfer methods from instrument to instrument in a simple way.

Raman spectroscopy was used to control a semi-batch polymerization reaction. Kaiser Raman data enabled open-loop and closed-loop feedback control, allowing production of materials with consistent quality.

A novel approach in Raman spectroscopy enables bulk material analysis without the need for specialized equipment. Enhanced Raman reflection can be integrated into current processes using available instrumentation, enabling real-time process measurement and control.
