Paramagnetic reagents for the study of the structure of heteroatomic compounds from the NMR spectra

Probing the Surface Structure of Divalent Transition Metals Using Surface Specific Solid-State NMR Spectroscopy

“…The observed 1 H T 1 can be thought to contain contributions from two separate interactions through the relation 1/ T 1 = 1/ T 1 P + 1/ T 1 dia where 1/T 1P is the contribution from the paramagnetic species, and 1/T 1dia is the contribution from all other diamagnetic interactions (e.g., 1 H– 1 H spin diffusion, and 1 H– 29 Si dipole coupling) . The paramagnetic contribution here is proportional to the distance (r) between 1 H and the paramagnet center and the number of the paramagnetic species (N P ) 1/ T 1 P α N P · 1/ r 6 …”

The study of structure and dynamics of molecules: NMR spectra transformed by superfine coupling

“…A reason of specificity of the NMR phenomenon in paramagnetic systems can be rationalized follows (see and the references cited therein). If resonant nucleus (for example, proton) is present in a paramagnetic molecule, i.e.…”

Organic analytical reagents in nuclear magnetic resonance spectroscopy

“…A number of general reviews [12,[45][46][47][48][49][50][51][52][53][54][55] and two practical guides [56,571 have appeared since then; another practical guide is in press [58]. The thd and fod complexes of praseodymium, europium, gadolinium, dysprosium, holmium and ytterbium are commercially available [59,60];…”
