Abstract : Within recent years proton magnetic resonance has become a tool of prime importance for the elucidation of the structure of organic molecules. Since all organic compounds contain 1 per cent carbon-13 in natural abundance, the study of carbon-13 nuclear magnetic resonance (nmr) spectra should yield a wealth of information concerning the bonding and electron distribution within organic molecules. Several approaches to account for chemical shifts and spin-spin couplings were proposed for exploration. One method involved the systematic study of substituents effects. Since nmr measurements are made on compounds in liquid solvents, the factors which contribute to solvent effects must also be understood. The current investigation, then, is concerned with probing and hopefully elucidating the many factors involved in nuclear magnetic resonance phenomena, with particular emphasis on carbon-13. The material contained in the report is that which has not yet been published either due to incompleteness or newness. (Author)
