Double-resonance magic angle coil spinning.
We present an extension of magic angle coil spinning (MACS) solid-state NMR spectroscopy to double-resonance experiments, enabling implementation of powerful double-resonance solid-state NMR methodologies including cross polarization, proton decoupling, and two-dimensional correlation spectroscopy etc., while still enjoying the merits that are intrinsic to MACS, such as high concentration sensi...
متن کاملMicrofabricated Inserts for Magic Angle Coil Spinning (MACS) Wireless NMR Spectroscopy
This article describes the development and testing of the first automatically microfabricated probes to be used in conjunction with the magic angle coil spinning (MACS) NMR technique. NMR spectroscopy is a versatile technique for a large range of applications, but its intrinsically low sensitivity poses significant difficulties in analyzing mass- and volume-limited samples. The combination of m...
متن کاملSingle Chip Probe for High Resolution Magic Angle Coil Spinning Nmr of Biological Samples
We report a single-chip probe for “magic angle coil spinning”-MACS nuclear magnetic resonance (NMR) spectroscopy. The probe consists in a wirebonded microcoil integrated with an on-chip interdigitated capacitor. This LC-circuit is resonant at 500 MHz (H Larmor frequency at 11.7 T) enabling wireless inductive coupling of the NMR signal and spinning for high resolution NMR. We demonstrate stable ...
متن کاملElectromagnetic-Induced Quench of an Inner-Shim Coil for a REBCO High-Temperature Superconducting NMR Magnet
A RE(rare earth)Ba2Cu3Ox (REBCO) high-temperature superconducting (HTS) coil is a promising candidate to achieve a nuclear magnetic resonance (NMR) magnet operated at a magnetic field >23.5 Tesla (T), i.e. 1 H NMR frequency of 1 GHz. We developed and tested a 400 MHz (9.39 T) NMR magnet using an REBCO inner coil. The system included a low-temperature superconducting (LTS) shim coil inside the R...
متن کامل“Magic Angle Precession”
An advanced and exact geometric description of nonlinear precession dynamics modeling very accurately natural and artificial couplings showing Lorentz symmetry is derived. In the linear description it is usually ignored that the geometric phase of relativistic motion couples back to the orbital motion providing for a non-linear recursive precession dynamics. The high coupling strength in the no...
