The 2,5-di-tert-butyl-3,4-dimethoxycarbonyl-pyrryloxyl radical has the small est line-width and the smallest nitrogen hyperfine splitting reported for a stable nitroxide. The influence of long range proton splittings was shown by selective and total

1,4-Bis(4‘,4‘-dimethyloxazolidine-N-oxyl)cyclohexane (1), a “fast exchange” biradical in which the principal directions of the g and D tensor are different, has been studied by ESR at low temperature at 245 and 294 GHz. These frequencies corr

Ions can be selectively rejected from the r.f.-only collision cell of a tandem quadrupole mass spectrometer, using an auxiliary r.f. field tuned into their characteristic transverse frequency. The efficiency of this method was studied on a mixture of
