In this work two examples in nanomaterials and interfacial chemistry are described where critical atomic level structural details, as well as information on dynamics, were obtained by the use of solid state NMR spectroscopy in conjunction with computational and related experimental approaches. Based on the 13C and 15N assignment, we arrived at an almost complete solid-state NMR assignment of proton signals by means of heteronuclear dipolar correlation spectroscopy, using indirect 1H detection. This leads to the 71Ga species being located in chemically and electronically more ordered molecular environments near the periphery of the nanoparticle, and hence improved photoluminescence. In Chapter 7, the structural information contained in the chemical-shift was exploited by analysing the differences in solution and solid-state NMR chemical-shifts of the SH3 domain.

A second, highly mobile CH3ReO3 species is primarily found at higher catalyst loadings, and was determined to be bound by hydrogen-bonding to surface silanols.

However, formatting rules can vary widely between applications and fields of interest or study.
These experiments provide a picture of the atomic and molecular distribution on the surface and the interior of the nanoparticle, and show that etching with HF results in significant reorganization of the InGaP nanoparticle surfaces and removal of surface defects.
This thesis demonstrates the forthcoming role of solid-state MAS NMR as a mainstream technique for structural investigation of proteins, as a method complementary to solution NMR and single-crystal diffraction. The work is disserration available. In the second part of this work the effect of rather different interfacial interactions are dussertation, namely those of structural changes following surface treatments on the optical properties of nanoscale Group III-V semiconductors and their ternary analogs.
This work demonstrates that the olefin metathesis activity is correlated with the presence of Lewis acid activated CH3ReO3, so that a material with high 10 wt. The 13CC long-range correlations obtained with the PDSD recoupling method were converted into distance restraints using an empirical approach.
Structure determination of immobilized proteins by solid-state NMR spectroscopy
Based on the 13C and 15N assignment, we arrived at an almost complete solid-state NMR assignment of proton signals by means of heteronuclear dipolar correlation spectroscopy, using indirect 1H detection. Nitrogen spins form a less dense network of spins than disserrtation nuclei. In Chapter 8, we investigated in more detail the mechanism of magnetization transfer in 15NN proton-driven spin diffusion experiments between 15N spins.
