I.R.-Spektren von [1,4—13C2]-Cyclohexandion-(1,4) und [1,4—13C2-Benzochinon-(1,4)

Abstract

The shifts of the infra-red frequencies of [1.4—¹³C₂]-cyclohexane-(1.4)dione and [1.4—¹³C₂]-p-benzoquinone in the solid state, in solution, and in the vapour phase are discussed in relation to band assignments given in the literature.
