INEPT INADEQUATE spectroscopy

Summary Many cyclic and linear transition metal-silicon compounds have been obtained by the elimination of alkali halides. The structures of these complexes were determined by INEPT and INEPT-INADEQUATE NMR spectroscopy. 

Si INEPT-INADEQUATE NMR spectroscopy afforded further evidence for the nortricyclene structure of 7 as the coupling constants (Fig. 4) are consistent with the proposed atom arrangement. 

There are a large number of structural parameters for NMR of different nuclei and many examples of how they can be applied to the analysis of hydroxylamines, oximes and hydroxamic acids. Fortunately though, there are many very clear, meticulously written descriptions of INEPT, DEPT, INADEQUATE, COSY, NOESY and the like, in one- and two-dimensional NMR spectroscopy, that are cited in the references. Since their content is beyond the scope of the present chapter, a brief mention of some of the fundamental concepts that are essential for its understanding by the nonspecialist is in order.
