- 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...

Access Document
Why is the content I wish to access not available via ORA?
Bibliographic data (the information relating to research outputs) and full-text items (e.g. articles, theses, reports, etc.) arrive in ORA from several different sources. Unfortunately we are not able to make available the full-text for every research output.
Please contact the ORA team (
) if you have queries regarding unavailable content OR if you are aware of a full-text copy we can make available.
) if you have queries regarding unavailable content OR if you are aware of a full-text copy we can make available.
Content may be unavailable for the following four reasons
Alternative access to the full-text
You may be able to access the full-text directly from the publisher's website using the 'Publisher Copy' link in the 'Links & Downloads' box from a research output's ORA record page. This method may require an institutional or individual subscription to the journal/resource.
