The 13 C NMR spectra of copolymers of ethylene with 4-methyl-1-hexene and 4-methyl-1-pentene, respectively, were compared. The 4-methyl-1-hexene/ethylene copolymer, which contains an unsymmetric 2-methylbutyl branch, exhibits two distinct 13 C NMR peaks for each of the pairwise methylenes spaced one

Abstract
Literature and unpublished data on alkylbenzenes have been analysed to give phenyl substituent effects. The effects have been determined for non‐α‐branched, α‐branched and α,α‐branched alkyl groups.

## Abstract The general correlation between the electron densities and the ^13^C NMR chemical shifts is found to be quite poor in the cases discussed. The non‐additivities of the substituent effects on the chemical shifts and the CNDO/2 electron densities correlate only weakly. However, when the el
A series of 3-substituted(X)bicyclo [ 1.1.1 ] pent-1-yltrimethylstannanes (3) were synthesized and their 119Sn and 13C NMR spectra were recorded. The 119Sn substituent chemical shifts (SCS) and the one-bond carbon-tin coupling constants [ 1J(13C,119Sn) ] were analyzed in terms of possible substituen
