Experimental proof of the existence of a fourth stable gas phase C2H4O+? isomer: the open ethylene oxide ion

Abstract
An ion cyclotron resonance study of the reactions of the C2H4O+˙ ion from ethylene oxide and 1,3-dioxolan and their deuteriated derivatives supports the existence of CH2 [graphic omitted]–ĊH2 as a stable gas phase entity in agreement with theoretical predictions.
