A major problem in the use of i3C-NMR spectroscopy for structure identification is to estimate the 13C shifts of compounds known or suspected to be present in the spectrum. The substituent chemical shifts of different functional groups were studied and new, detailed empirical rules are reported. Tre

In the last decade, in vivo MR methods have become established tools in the drug discovery and development process. In this review, several successful and potential applications of MRI and MRS in stroke, rheumatoid and osteo-arthritis, oncology and cardiovascular disorders are dealt with in detail.
Ab initio calculations show that additivity of the intermolecular shielding exists in a model system consisting of fluorobenxene interacting with hydrogen fluoride molecules, C&F-( HF),, where n= l-5. These results indicate that it should be possible to perform chemical sbieldiig calculations on a l
