About this mock
UGC-NET Forensic Science Unit II drill on spectrophotometry at the method-selection band. Scenarios cover UV-Vis lamp and solvent choice, FTIR sample preparation (KBr disc, Nujol mull, ATR), Raman selection rules and portable 1064 nm advantage, Beer-Lambert quantitation, drug confirmation per SWGDRUG, paint binder identification by carbonyl-region IR, fibre identification by ATR-FTIR, ink discrimination by UV-Vis-NIR microspectrophotometry, and COHb estimation. Companion to the easy band on the same syllabus area.
