Can you do NMR on a solid?
Solid particles will not show up in a solution NMR spectrum, and may interfere with proper shimming.
What is the Hetcor NMR?
HETCOR is a 2D NMR experiment where two different types of nucleus are correlated through single bond spin-spin couplings. Today HETCOR is used occasionally, as the more sensitive HSQC experiment is giving similar information.
How do you prepare a sample for solid state NMR?
Sample prep: Solid state NMR is done using ‘rotors’ of various outer diameters (1 mm – 7 mm usually), usually made of zirconia. The solid samples are packed inside these rotors. It is a bit more involved and time-consuming than solution-state sample prep.
Is Solid state NMR destructive?
Solid-state magic angle spinning (MAS) NMR provides structural information on powder amorphous solids for which single-crystal diffraction structures cannot be obtained. NMR is non-destructive; the powder sample may be used for further studies.
What does solid-state NMR tell you?
Abstract. Solid-state nuclear magnetic resonance (NMR) spectroscopy is an atomic-level method to determine the chemical structure, 3D structure and dynamics of solids and semi-solids.
Is 35cl detectable by NMR?
Use our NMR service that provides Cl NMR and many other NMR techniques. (Cl) Chlorine has two useful NMR active nuclei 35Cl and 37Cl. Both yield relatively broad signals but have a broad chemical shift range.
What is Hector spectrum?
HETCOR is a 2D NMR experiment that identifies proton-carbon correlation. The carbon spectrum is on one axis (the x-axis here) and the proton spectrum is on the other axis (the y-axis here). The spectrum is a contour map. The peaks identify which proton and carbon peaks are correlated.
How much sample do you need for solid state NMR?
For 13C NMR between 10 and 50 mg of sample is recommended. If you do not have enough sample or cannot achieve high enough solubility, it may still be possible to obtain a spectrum although it is recommended that you request 500 MHz service and the spectrum will take longer to acquire.
Why are solid-state NMR signals generally much broader than solution state NMR?
For solution state NMR, chemical shift and J-coupling (spin-spin splitting) are the incterations basically influence the resulting spectra. So both of the interactions have significant effect in the solid-state NMR, which results in much more broad peaks instead of narrow peaks in solution-state NMR.
