WebTherefore the same or similar functional groups in different molecules will typically absorb within the same, specific frequency ranges. Consequently tables of IR absorptions are arranged by functional group -- it some … 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.
