Abstract
NMR chemical shift is a molecular property that can be computed from first principles. In this work we show that by utilizing our combined fragmentation method (CFM), one is able to accurately compute this property for small proteins. Without nonbonded interactions, the root mean square errors (RMSEs) compared to the full calculations for (1)H, (13)C, (15)N, (17)O and (33)S were 0.340, 0.649, 3.052, 6.928 and 0.122 ppm respectively, while with the inclusion of nonbonded interactions the RMSEs for (1)H, (13)C, (15)N, (17)O and (33)S were 0.038, 0.253, 0.681, 3.480 and 0.052 ppm respectively.

Chemical shift correlation at high MAS frequencies employing low-power symmetry-based mixing schemes
Abstract An approach for conveniently implementing low-power CN n ν and RN n ν symmetry-based band-selective mixing sequences for generating homo- and heteronuclear chemical shift correlation NMR spectra of low γ nuclei in biological solids is demonstrated. Efficient magnetisation transfer characteristics are achieved by selecting appropriate symmetries requiring the application of basic RF elements of relatively long duration and numerically tailoring the RF field modulation profile...

A simple method for measuring signs of 1HN chemical shift differences between ground
Abstract NMR relaxation dispersion spectroscopy is a powerful method for studying protein conformational dynamics whereby visible, ground and invisible, excited conformers interconvert on the millisecond time-scale. In addition to providing kinetics and thermodynamics parameters of the exchange process, the CPMG dispersion experiment also allows extraction of the absolute values of the chemical shift differences between interconverting states,
