We manufacture and distribute fine chemicals and laboratory products - with quality and delivery you can count on every time. This reinforces the care you have to take in trying to identify any absorptions in the fingerprint region. Surface-enhanced Raman scattering (SERS) spectrum was recorded on a silver colloid.

Notice: This spectrum may be better viewed with a Javascript values cannot be derived. The molecule is adsorbed on the silver surface with the benzene ring in a ‘tilted orientation’. evaluated IR Spectrum Table by Frequency Range. Nogueira d Katerina Castkova Again, there is no trough due to the O-H bond, and again there is a marked absorption at about 1700 cm-1 due to the C=O. In fact this absorption would be at a higher number still if the alcohol isn't hydrogen bonded - for example, in the gas state. The molecule is adsorbed on the silver surface with the benzene ring in a 'tilted orientation'. The other really useful bond is the O-H bond.

Confusingly, there are also absorptions which look as if they might be due to C-O single bonds - which, of course, aren't present in propanone. What it means is that you can ignore a trough just under 3000 cm-1, because that is probably just due to C-H bonds. In fact this absorption would be at a higher number still if the alcohol isn't hydrogen bonded - for example, in the gas state. FT-IR and FT-Raman spectra of methyl(2-methyl-4,6-dinitrophenylsulfanyl)ethanoate were recorded and analyzed. Surface-enhanced Raman scattering (SERS) spectrum was recorded on a silver colloid. However, NIST makes no warranties to that effect, and NIST 7a. Select a region with data to zoom. You couldn't be sure that this trough wasn't caused by something else.
