摘要:
Two-dimensional indirectly detected through-space and through-bond H-1{N-15} solid-state NMR experiments utilizing fast magic angle spinning (MAS) and homonuclear multipulse H-1 decoupling are evaluated. Remarkable efficiency of polarization transfer can be achieve data MAS rate of 40kHz by both cross-polarization and INEPT, which makes these methods applicable for routine characterizations of natural abundance solids. The first measurement of 2D H-1{N-15} HETCOR spectrum of natural abundance surface species is also reported. (C) 2013 Elsevier Inc. All rights reserved.
