Identification Result
36%The sample exhibits a spectral pattern dominated by intense alkyl C–H stretching, scissoring, and rocking modes, indicating a structure composed mainly of long methylene sequences. The overall profile is most consistent with a saturated aliphatic hydrocarbon, such as polyethylene, although the low library similarity precludes definitive identification 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.
