Identification Result
0%The library search leaves POLYVINYL CHLORIDE as the nominal top hit, but the match quality is effectively non-discriminating and the observed spectrum is not specific enough to support a firm PVC assignment. The sample is more defensibly described as an oxygenated organic material showing aliphatic C-H stretching, a carbonyl band near 1727 cm-1, and broad O-H/N-H region absorption between about 3439 and 3695 cm-1. That evidence is more consistent with a broad oxygen-containing organic or polymeric material than with a clean identification as polyvinyl chloride alone
