The Fundamentals of Infrared Spectroscopy
www.midac.comof infrared spectroscopy the wavelength of light incident on the detector at a given time is known. This is called DISPERSIVE spectroscopy because the light is dispersed into its component wavelengths. In many cases, however, the optics are more complex. In the case of Fourier Transform infrared spectroscopy (FTIR), the optics include an
Guide to the identification of microplastics by FTIR and ...
assets.thermofisher.comecosystem. Fourier Transform Infrared (FTIR) and Raman spectroscopies have long been used for the analysis of polymers, and it is, therefore, natural that they be the de facto techniques to identify microplastics. This note provides an overview of FTIR and Raman techniques as applied to the identification of microplastics.

Infrared Spectroscopy
mmrc.caltech.eduInfrared (IR) spectroscopy is one of the most common spectroscopic techniques used by organic and inorganic chemists. Simply, it is the absorption measurement of different IR frequencies by a sample positioned in the path of an IR beam. The main goal of IR spectroscopic analysis is to determine the chemical functional groups in the sample.
