The Role of the Chemical Shift Difference in a Two-Site Exchange Model Under an On-Resonance Spin-Lock RF Field
Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.

The manuscript investigates the role of the chemical shift difference between two exchanging pools under a spin-lock RF field. The results demonstrate that the width of the dispersion of R1rho is determined mainly by the chemical shift difference when the exchange is slow. This work may give a new insight into the spin dynamics under a spin-lock condition and the results may be relevant to the fields using the spin-lock technique, such as protein NMR and MRI contrast.
