N. Logan scatterer we mean a potential or an obstacle. It also gives necessary and sufficient conditions for a domain to be a ball if an overdetermined boundary problem for the Helmholtz equation in this domain is solvable. This includes a proof of Schiffer‘s conjecture, the solution to the Pompeiu problem,

Experimental Aspects of Nitrogen NMR,evoid of theoretical details on the one hAND and details of electronic circuitry on the other. Since the required techniques are obviously not restricted to nitrogen nuclei solely, they have been individually, but not collectively, covered in detail elsewhere, as will be pointed out.

Correlations of Nitrogen Coupling Constants with Molecular Structure,ation of nitrogen spin-spin couplings as an aid in spectral analysis and structure elucidation. Although present theory is unable to predict accurate values of these couplings, a knowledge of the range of coupling constants found for different molecular systems has considerable potential for structu

Applications of 14N NMR Data in the Study of Inorganic Molecules,of nitrogen compounds. For example, the last few years have witnessed an extensive and rewarding application of the technique in organic chemistry (Chapter 4). Three recent general reviews of nitrogen nuclear magnetic resonance including both .N and .N, show that less attention has been paid t

Book 1973this book to provide a comprehen sive account of the widely spread applications of nitrogen NMR. The relevant literature has been surveyed from the beginnings of NMR until early 1972. The steady annual growth in the number of references cited since 1965 is ample evidence of the ever increasing impo
