近年来,固体核磁共振波谱学得到了迅猛发展,新的实验方法和技术层出不穷,在多相催化、材料科学及生物大分子的研究中得到日益广泛的应用。为了推动我国固体NMR领域的研究进展,中科院武汉物理与数学研究所波谱与原子分子物理国家重点实验室、国家大型科学仪器中心·武汉磁共振中心将与法国里尔一大强磁场中心联合举办“第四届中法固体核磁共振波谱学讲习班”(4th Sino-French Workshop on Sol...
All-atom molecular dynamics (MD) simulation and the NMR spectra are used to investi-gate the interactions in N-glycylglycine aqueous solution. Different types of atoms exhibit different capability in ...
There exist a variety of multi-pulse NMR experiments for spectral editing of complex molecules in solution. Maximum quantum correlation NMR spectroscopy (MAXY NMR) is one of the techniques for disting...
PENDANT 13C NMR Spectroscopy Applied to CHn Groups     PENDANT  13C NMR  Product Operator Theory       font style='font-size:12px;'> 2010/4/9
Polarization enhancement nurtured during attached nucleus testing (PENDANT) NMR spectroscopy gives signals of quaternary carbon atoms in addition to signals indicative of CH, CH2 and CH3 groups. In th...
We revisit the phenomenon of quantum stochastic resonancein the regime of validity of the Bloch equations. We find that a stochastic resonance behavior in the steady-state response of the system is pr...
Product operator formalism is widely used for analytical description of multiple-pulse NMR experiments for weakly coupled spin systems. 3D J-resolved NMR spectroscopy is widely used in order to resolv...

The Cl NMR spectroscopy of Cl -intercalated hydrotalcite and the Ca-aluminate hydrate, the presence of hydrocalumite (Friedel°Os salt) demonstrates dynamical behavior of interlayer C dynamical orde...
A magic-angle-spinning nuclear magnetic resonance (MAS NMR) spectroscopic study was done on the series of synthetic gallian-fluor amphiboles to identify the extent of Ga and Si ordering in the Si MA...
High-resolution 25MgNMR data are reported for a single crystal of pure forsterite (Mg2Si04) at temperatures to about 1400°C, which allow rates of exchange ofMgcations among specific sites in the struc...
