What is Vibrational Spectroscopy?

Vibrational spectroscopy is the collective term used to describe two analytical techniques – infrared and Raman spectroscopy. Infrared (IR) and Raman spectroscopy are non–destructive, non–invasive tools that provide information about the molecular composition, structure and interactions within a sample. These techniques measure vibrational energy levels which are associated with the chemical bonds in the sample. The sample spectrum is unique, like a fingerprint, and vibrational spectroscopy is used for identification, characterisation, structure elucidation, reaction monitoring, quality control, and quality assurance.
