This book serves as an introduction to the structure dependence of 1H chemical shifts and couplings and to the methods used to model 1H NMR spectra. It is also an introduction to the CHARGE computer program. This program predicts the 1H chemical shifts and couplings of any organic compound from the molecular structure. It is incorporated into the NMRPredict package which uses molecular mechanics to generate the molecular conformation of the compound studied. The CHARGE program then predicts the 1H chemical shifts and couplings of the compound and the NMRPredict software then calculates and displays the resulting 1H NMR spectrum. Both the CHARGE and the NMRPredict programs are provided on a CD-ROM with the book, with detailed examples of molecular input and output for both of them. A comprehensive list of ca 500 assigned 1H NMR spectra, with observed vs calculated chemical shifts is given in the appendix.
