Dario Prandi,Jean-Paul Gauthierlvent effects are expected to be greater in .N spectroscopy than in carbon NMR. Examination of Table 5.1 shows that amines, amides (or ureas), nitriles and nitro derivatives are characterized by different values of polarity parameters indicatory of their electron-donating or -accepting abilities.

Interventions into the Scenes of Conflicties concerned are short or long with respect to the NMR time scale. In fact, information about molecular dynamics corresponding to very fast motions, is obtained by relaxation time determinations, and this topic has already been discussed in Sect. 2. Here we shall be concerned with chemical exchange

15N Chemical Shifts,al most too numerous to count. Yet our knowledge of the basic principles of congenital hip dislocation and its management is constantly being expanded by new research. In Germanspeaking countries, Kaiser pub lished the last comprehensive textbook on congenital hip dislocation in 1958, and Schlegel
