Free radicals by mass spectrometry, XLVII. lonization potentials and ionic heats of formation of C5–C7 alkyl radicals

Abstract

Using an energy-resolved electron beam, ionization potentials have been measured for a number of C5–C7 isomeric alkyl radicals, produced by pyrolysis of nitrite intermediates. Values for primary radicals, which could not be produced in sufficient yield, are estimated by extrapolation from lower members of the series. Ionic heats of formation and hydride ion affinities are reported.
