aliphatic hydrocarbon material with possible minor oxygen-containing functionality
Sample & Measurement Parameters
Identification Result
0%The present FTIR pattern is dominated by aliphatic C-H stretching and bending bands, with paired low-wavenumber rocking bands consistent with a long methylene-rich hydrocarbon chain. The library search does not provide a reliable named identification, and the broader Top-15 pattern only weakly suggests oxygen-containing motifs. Because the measured peak set lacks a characteristic carbonyl or other clearly identifying heteroatom band, the most supportable conclusion is an aliphatic hydrocarbon material, while allowing for possible minor oxygen-containing functionality that is not securely established from the current spectrum
