oxygenated unsaturated organic material, possibly a polymeric or copolymeric material containing carbonyl and C–O functionality
Sample & Measurement Parameters
Identification Result
0%The current FTIR evidence does not support a firm material identification. The library top hit is Vinyl chloride/vinyl acetate copolymer, but all listed library similarities are effectively non-discriminating, and no direct or related literature evidence narrows the assignment. The observed bands are more securely interpreted as an oxygenated organic material with a carbonyl band near 1710 cm-1, C–O stretching near 1107 cm-1, aliphatic C–H near 2953 cm-1, and unsaturation indicated near 1640 and 961 cm-1. A polymeric or copolymeric organic material remains plausible, but the present evidence is too weak to defend the specific library name as the sample identity
