Doing an exchange term so I've missed some classes that the others have attended, and unfortunately we're getting contradictionary explanations, so I thought I'd try and ask you.
Would be extremely thankful if someone could explain the effect of conjugation of a carbonyl group on the resonance frequency in IR spectroscopy.
Our 'assignment' is basically to figure out if it's supposed to be lower or higher than an unconjugated carbonyl.
Thanks in advance!
