WebThe figure given above represents the IR spectrum of phenol. There is an OH stretch at 3345 cm⁻¹ . There is a bend at 1367 cm⁻¹ , which has the wave number in the same range as that of a -CH₃ group. This peak does not correspond to a -CH₃ group as it is too broad and there are no stretches of methyl C-H below 3000 cm⁻¹.
WebSince every functional group is composed of different atoms and bond strengths, vibrations are unique to functional groups, and classes of functional groups (e.g. O-H and C-H stretches appear around 3200 cm -1 and 2900 cm -1, respectively).
