Intermolecular Dipolar Interaction in Diamagnetic and Paramagnetic Solution

This contribution to the PRE is called inner-sphere relaxation. The ligand or solvent molecules can also experience PRE without ever entering the inner coordination sphere of the paramagnetic species. This second mechanism, referred to as outer-sphere (OS) relaxation, is usually less important and more 

Kateb and Piccioli proposed a new pulse sequence to measure cross correla- 

Rast et al. studied the mechanisms of the intermolecular NMR relaxation dispersion of the tetramethylammonium protons in Gd heavy-water solutions. The standard dipolar nuclear relaxation formalism of Solomon-Bloembergen, valid for the used frequency range between 10 and 800 MHz, leads to overall good agreement with the measured data without any adjustable parameters. Madhu et al. reported experimental observation and numerical simulation of a two-dimensional multiplet effect in the heteronuclear correlation spectrum of a paramagnetic protein that depends on molecular geometry. Bertini et performed solution structure calculations through self-
