Enhancement of water suppression by radiation damping-based manipulation of residual water in Jump and Return NMR experiments
It is shown in this Letter that amplification of radiation damping obtained by electronic feedback between consecutive transients of a Jump-Return (JR) experiment, residual in-plans water magnetization is suppressed, leading to substantial enhancement of water suppression. Application of this approach to RNA spectroscopy, where JR is particularly useful, is shown.
