PMR spectra of thirty-eight chloromethylthiopliene and seven dithienylmethane derivatives were observed at 60 or 40 MHz. The cheniical shifts of methylene protons were 4-63 to 5.25 ppni for monosubstituted 2-chloromethylthiophenes and 4.37 to 4.56 ppm for inonosubstittited 3-chloromethylthiophenes,
## Abstract The chemical shifts and coupling constants for the ring protons of nine disubstituted naphthalenes (mainly halogenonitre compounds) in carbon tetrachloride solutions have been obtained by analysis and computer simulation of their 100 MHz magnetic resonance spectra. Substituent effects a
## Abstract An accurate measurement of the chemical shifts and the coupling constants of some disubstituted acetophenones has been made. The acetophenones studied contained nitro, bromo or amino groups substituted in either the 3,4 or 2,5 positions. For compounds with no substituent adjacent to the
## Abstract The n.m.r. spectra of some 1,2,2βtrisubstituted cyclopropanes are reported. Coupling constants and chemical shifts of the cyclopropane protons and their dependence on substituent effects are discussed. Conformations of benzylcyclopropane derivatives are investigated by long range magnet
