Photo-CIDNP experiments with an optimized presaturation pulse train, gated continuous illumination, and a background-nulling pulse grid.

Abstract:

Methods to record chemically induced dynamic nuclear polarization (CIDNP) spectra that are virtually free from background magnetization and avoid the sensitivity loss and subtraction artifacts of difference spectroscopy have been developed. Presaturation by a string of composite pi/2 pulses, each followed by a defocussing field gradient, is analyzed, and guidelines for the optimization of pulse phases and gradient strengths are derived. Subsequent gated illumination during a grid of pi pulses...
