Studies of the genesis of the [M − H] + ion in flavanone and 2′‐hydroxychalcone, performed with the aid of metastable decompositions and deuterium labelling, allow new structural notations to be postulated for the [M − H]+ ions, which in turn provide evidence for the pathways in the [M − H – ketene]+ fragmentation routes for these compounds.
