Moreover, the surface NMR measurements may be affected by gradients in the geomagnetic field, which can induce the protons to oscillate at a slightly different fL. The Geophysical Institute of the University of Alaska has several stations across the state to monitor the geomagnetic field activity ...
The thermal polymerizations of these complexes were carried out in the solid state and in the melt. Structural analyses of polymers were performed by 1H-NMR, 13C-NMR, and FTIR spectroscopic analyses; Tg by differential scanning calorimetry; as well as the molecular weights by viscometrical ...
The solid-state physicochemical characteristics of the sertraline–β-CD complex were investigated by the phase solubility method, differential scanning calorimetry, Fourier transform IR spectroscopy, FT-Raman spectroscopy, powder X-ray diffraction, and 13C cross-polarization magic-angle spinning NMR ...
Density functional theory (DFT)1 is the main working horse for material simulations, especially for ground-state properties such as atomic structures and binding energies. However, it is well known that the DFT, in particular the Kohn-Sham eigen energy2, significantly underestimates band gaps. ...
