https://doi.org/10.1007/978-1-349-81780-1t of nitrogen spectroscopy is indeed very recent. This is due to the fact that nitrogen-14, which is the naturally abundant isotope, suffers, for structural studies, from the disadvantages inherent in nuclei with a quadrupolar moment (Table 1.1). Actually, indirect .N measurements were reported in t

A Self-Help Guide to Managing Depression of .N parameters have been obtained in the past through CW double resonance experiments. In this area, the various techniques of .H{.N}double irradiation can be exploited and information about the .N resonances is then obtained via proton responses to perturbations applied, more or less selectively
