Magnetic multiple resonance techniques

The use of single resonance experiments for sign determination depends on the presence of second-order features which in favorable cases incidentally lead to relative sign information. This has been widely used in magnetically inequivalent systems such as AA XX. While the early relative sign data were obtained in this fashion, multiple resonance techniques are the preferred direct method.

Linkages progress in many ways and instances. Many are catalyzed by ever widening capabilities of instrumental skills, exemplified by the study and use of nuclear magnetic resonance techniques. The joining of intellectual approaches and skills between disciplines will create major and basic advances such as to have multiple impacts on many branches of biomedical science. 

Among the multiple spectroscopic techniques that can provide information about the catalytic active sites under reaction conditions (Raman, IR, UV-vis, X-ray absorption (EXAFS (extended X-ray absorption fine structure)/XANES (X-ray absorption near edge structures)), nuclear magnetic resonance (NMR), electron sprin resonance (ESR), etc.), Raman spectroscopy is the technique of choice because of...
