## Abstract The spectra of several 2βmethylβ6βRβdisubstituted naphthalenes (R=H, Me, I, NO~2~, Cl, SO~2~Cl, OH, OMe, COMe, Br, F and NHCOMe), have been analysed. Chemical shift and coupling constant values of these compounds are presented. The proton chemical shifts have been found to correlate wit

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 are essentially additive except when a strong Οβdonor group is in direct conjugation with a strong Οβacceptor group.

## Abstract The chemical shifts and coupling constants for the ring protons of fourteen monosubstituted naphthalenes in carbon tetrachloride solution have been obtained by analysis and computer simulation of their 100 MHz magnetic resonance spectra. Studies at several concentrations have enabled sh
## 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
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,
