Abstract:
Raman spectroscopy has been used as an in situ tool to obtain kinetic data for an organic transformation. The model reaction studied was the synthesis of 3-acetylcoumarin from the condensation between salicylaldehyde and ethyl acetoacetate with piperidine as a catalyst. The study shows that precise kinetic data can be obtained quickly and reproducibly, allowing for the facile determination of both overall reaction order and reaction order with respect to each component of the reaction. Additionally, Arrhenius parameters such as activation energy for a reaction can be readily obtained. In conjunction with computational modeling, this data-rich analysis technique also allows for in-depth probing of mechanistic aspects of reactions. Microwave heating proves to be an ideal tool for aiding in kinetic studies. It offers reproducible noncontact heating as well as precise temperature monitoring and data recording.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
