Collisionally activated charge reversal of HCOCH 2 − and CH 3 COCH 2 − produces positive ions whose fragments differ from those of other [C 2 H 3 O] + ions formed by fragmentation of positive molecular ions, including the [C 2 H 3 O] + ions from 2,2‐dichlorethanol, considered formerly to have the HCOCH 2 + structure. The fragmentations of the charge reversed ions are concordant with the RCOCH 2 + structures. Least‐squares correlations of the collisional activation spectra [C 2 H 3 O] + are probed as a useful guide to claiming similarity or dissimilarity of ionic structure.
