The use of deuterium as a nucleus for locking, shimming, and measuring NMR at high magnetic fields

Research output: Contribution to journalArticle

Abstract

The use of deuterated solvents for NMR field-shimming and -locking procedures at magnetic fields corresponding to a proton frequency of 300-400 MHz or higher is evaluated. It is shown that the appearence of quadrupolar splittings and interference of scalar deuterium-deuterium couplings influence lock sensitivity and stability for many deuterated solvents. The influence of self-decoupling on this process and on the detectability of quadrupolar couplings in the deuterium NMR spectrum is also discussed. A list of problematic and suitable lock solvents is presented.
