The relative intensities of the losses of ethyl groups from opposite sides of the 3‐pentanone ion formed by isomerization from its enol isomer are shown to be equal when corrections for protonated acrolein formation, isotope effects, and overlapping ethane losses are made. Thus the ion decomposes symmetrically, implying ergodic behavior, as concluded by Depke and Schwarz.
