## 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
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,
