WebThe infra-red spectrum for a primary amine. 1-aminobutane. Primary amines contain the -NH 2 group, and so have N-H bonds. These absorb somewhere between 3100 and 3500 cm-1. That double trough (typical of primary amines) can be seen clearly on the spectrum to the left of the C-H absorptions. WebIR Spectrum of phenol NMR Spectroscopy of phenol Phenol The chemical formula of phenol is C₆H₅OH. It is an aromatic compound consisting of a hydroxyl group which is attached to a phenyl group. It is mildly acidic. Phenol is formed when the decomposition of organic materials takes place.

WebIn the last spectrum, I wonder why two peaks at ~3100 cm-1 and 2900 - 2800 cm-1 have the very small intensity. I expect that those peaks belong to C = C bond and C(sp3) - H but it's too small, compared to the other spectrum (such as the first and the second in the video). Why is this happen and does it relate to the structure of the ketone ?
