Field-Cycling NMR Applied to Macromolecular Structure and Dynamics

Abstract

Field-cycling NMR (FCNMR) is defined as use of a sequence in which the main field is changed by more than a few millitesla,in order to study resonance and relaxation at a variety of fields,usually much lower than the observation field (Figure 1). Preparation often consists simply of waiting for nuclear magnetization to approach a high value. The entire field cycle takes place in a time shorter than,or sometimes comparable to,the relaxation time of the prepared spin species at the low field,and the detection part of the cycle is often a simple free induction decay after a 90° pulse,or some form of adiabatic rapid passage.
