| Abstract: | The valid magnetic field and the formula of inherent chemical shift in colunm medium under arbitrary conditions for NMR experiments were deduced.The chemical shift calibrations with single-spectrum,double-spectrum and magic-angle experiments were summarized.The medium magnetic effects in parallel and vertical magnetic fields were discussed in detail. |
