Spectroscopy E-Books
Scanning electron microscopy with energy dispersive X-ray spectrometry (SEMEDS) and Fourier-transform infrared microspectrophotometry (micro-FT-IR) have been widely demonstrated as complementary analytical tools for the identification of complex mixtures and unknown materials. However, there is a gap between the information provided by these two techniques.

Chemometric Analysis on ATR-FT-IR Spectra of Spray Paint Samples for Forensic Purposes
April 1st 2022Spray paint is often used by vandals for creating graffiti, as well as for criminals to leave signs, messages, and blots to conceal the left traces at the scene of their efforts. Rajinder Singh and his colleagues in the Department of Forensic Science at Punjabi University (Punjab, India) have used attenuated total reflectance Fourier transform infrared (ATR-FT-IR) spectroscopy for nondestructive analysis of 20 red spray paints of different manufacturers, which could possibly be encountered at a crime scene, particularly in case of vandalism. Singh spoke to Spectroscopy about the findings, and the paper that resulted from their efforts.
