Abstract
Dissociations of the molecular ions of neopentane, 2‐methylpentane, 2,3‐dimethyl butane and n‐octane, formed in charge‐exchange collisions with Hg+, were studied using an in‐line tandem mass spectrometer. The effect of collision chamber temperature upon the observed dissociations was examined. The results are in good agreement with previous calculations, based on the quasiequilibrium theory (QET) for unimolecular reactions and on the alkane photoionization data.
