Abstract:
A new and easily usable sample for adjusting the magic angle in a high resolution magic angle spinning (HR-MAS) probe head is a swollen polymer stick in CDCl(3) . The deuterium resonance shows a quadrupolar splitting if the rotor assembly is not at the magic angle, but a sharp singlet if the magic angle is correctly adjusted.

The internal reference compound generally used in NMR spectroscopy is tetramethylsilane (TMS). TMS is preferred because it is chemically inert, soluble in NMR solvents, and easily removable. Also, the highly shielded methyl protons in TMS yield an intense...
