摘要

Abstract: Measurement of the CH3+(Me') transfer equilibria, B'Me'+ B= B'+ MeB+, with a pulsed high-pressure mass spectrometer and an ion cyclotron resonance mass spectrometer led to a scale of relative methyl cation affinities of bases B, MCA (B). This scale when calibrated to the literature value for the Me+ affinity of N2 led to absolute MCA values for the other 24 bases B that were part of the scale. Rate constants for several Me+ ...
