A Novel Approach for Forensic Differentiation of Grass Stains Using ATR FT-IR Spectroscopy and Chemometrics

Grass evidence often encountered at the crime scene, helps in establishing the primary as well as secondary crime scenes. Due to the limited quantity and intricate nature of samples, there is a need for fast, sensitive and reliable techniques for the effective analysis of this vital evidence. In the current study, an attempt is made to study the feasibility of ATR FT-IR in combination with chemometric tools for chemical characterization and...
