Identification Result
36%The sample is best interpreted as a multicomponent organic material consistent with a plasticized or modified poly(vinyl chloride) that incorporates ether/ester and aromatic functional groups. This interpretation aligns with the spectral evidence and is supported by literature reports on related PEO-PVC systems FTIR In-Depth Interpretation was not selected for this task, so this section shows the library-search result only and no deep AI interpretation was run.
Detailed interpretation
- Top library match: Poly(vinyl chloride) #40512
- Some literature sources attribute the 1098 cm⁻¹ band to C-S stretching [4], but the ether C-O-C assignment is more consistent with the overall chemistry and the library direction.
- The low library match confidence and the heterogeneous nature of the assignments (e.g., syringyl ring breathing at 1329 cm⁻¹ from lignin literature) introduce ambiguity about the exact composition.
- The presence of methoxy and aromatic groups suggests the material is not pure PVC but rather a modified or plasticized variant; the specific modifying moieties cannot be definitively confirmed from FTIR alone.
