Multiply Charged (Di‐)Radicals

Abstract

A window of opportunity: New types of gaseous multiply charged (di-)radicals based on ionic liquids have been prepared by ESI MS/MS techniques by using imidazolium ion sites to act as “handles”. Dissociation of gaseous (CH2)n-bridged triimidazolium ions leads to groups of multiply charged (di-)radicals contained within a narrow window of one m/z unit (see spectrum).
