Experimental evidence for an asymmetric Xe2F3+ ion in the gas-phase

Xe2F3+ ions were prepared by high-pressure chemical ionization (CI), and structurally assayed by collisionally activated decomposition (CAD) and MS/MS/MS (MS3) mass spectrometry. A new asymmetric Xe2F3+ isomer was detected, to whom a [F–Xe–XeF2]+ connectivity can be assigned.
