The Basics of Infrared Spectroscopy and Its Recent Applications

Abstract

Infrared spectroscopy (IR) is a useful tool to identify unknown substances. In addition, it is easy to handle even for beginners of chemical analysis. In this review, the basics of several recent applications of IR such as photoacoustic spectroscopy (PAS), Attenuated total refrection (ATR) imaging and atomic force microscope (AFM)-IR are introduced.
