In-Situ Monitoring of Homogeneously Catalysed Reactions using Raman Spectroscopy Inside Hollow-Core Photonic Crystal Fibres

Abstract

We monitor the reaction of an acid with an alcohol inside a hollow-core photonic crystal fibre using Raman spectroscopy. The method uses tiny amount of chemicals and allows precise measurement of the activation energy.
