aliphatic hydrocarbon-type material with possible inorganic or weakly IR-active contribution
Sample & Measurement Parameters
Identification Result
0%The current FTIR evidence does not support a firm material identification. Although the nearest library entry is Iron, the reference library comparison is non-discriminating because the top candidates all have zero similarity and show no consistent supported functional groups. The sample spectrum is instead characterized by bands at 2924 and 2856 cm-1, consistent with aliphatic C-H stretching, plus bands near 1459 cm-1 and 1012 cm-1, which can occur in hydrocarbon-containing materials but are not sufficiently specific to assign a unique compound. On the present evidence, the most defensible conclusion is a broad aliphatic hydrocarbon-type material, potentially mixed with an inorganic component or another weakly IR-active phase
