nitroxide radical for Overhauser

[John Smith]

does anyone know a suitable radical/solvent mix ( sounds like a students cocktail :-) to use in an Overhauser mag?


I see the LETT one uses "Tempone", but a search on that leaves me baffled ( never was much good at chemistry/ nuclear physics )


I like the idea of using a lower power RF for the polarisation,( battery saving ) and it gets a higher level of polarisation ( better sensitivity )
