Single-crystal NMR spectroscopy [PDF]

Progress in Nuclear Magnetic Resonance Spectroscopy, 2021
Single-crystal (SC) NMR spectroscopy is a solid-state NMR method that has been used since the early days of NMR to study the magnitude and orientation of tensorial nuclear spin interactions in solids. This review first presents the field of SC NMR instrumentation, then provides a survey of software for analysis of SC NMR data, and finally it highlights
