The carbon chemical shifts values in the CMR spectra of monomethylalkanes of general formula Nn (where n is the letter designation of linear alkane, and N is the carbon atom numbers which are attached to the methyl groups in the alkyl chain of n) of four monomethylalkane families (2n, 3n, 4n and 5n) have analyzed. It is calculated and discussed the individual (Nn-i) "standard" differential parameters (the difference between absorption of studied carbon nuclei in all 4 types of Nn and its absorption in the lalkane n) and the "integral spectral changes" Σ N-n-i that occur in process n → Nn.

Phenylglyoxal (I) addiert tert.‐Butylhydroperoxid (II) zur Titelverbindung (III) mit photolabiler Benzoyl‐ und thermolabiler Peroxidgruppe am selben C‐Atom.

The concept of "compatible" and "incompatible" CMR spectra has been introduced. Application of compatibility increments (IC) allows to calculate the chemical shifts of C 2 and C 3 atoms of pentyloxyl fragment in 1-pentylbenzoylformate with a sufficiently good accuracy.
