An exact solution for R in CPMG experiments in the case of two site chemical exchange

Abstract:

The Carr-Purcell-Meiboom-Gill (CPMG) experiment is widely used to quantitatively analyse the effects of chemical exchange on NMR spectra. In a CPMG experiment, the effective transverse relaxation rate, R , is typically measured as a function of the pulse frequency, ν. Here, an exact expression for how R varies with ν is derived for the commonly encountered scenario of two-site chemical exchange of in-phase magnetisation. This result, summarised in Appendix A, generalises a frequently used eq...
