New chemical evidence for the ability to generate radical molecular ions of polyenes from ESI and HR-MALDI mass spectrometry

Author affiliations

Abstract

We report here new chemical evidence for the generation of radical molecular ions of compounds with a conjugated π-system (polyene) in ESI and HR-MALDI mass spectrometry. The oxidation potential of the neutral polyenes was calculated by cyclic-voltammetry and the results compared with those previously published for other complex conjugated compounds that have also been shown to form M˙+ in ESI-MS. This study clearly demonstrates the correlation between the oxidation potential and the formation of the M˙+ for the polyenes studied.
