Radical stability can be assessed by a new mass spectrometric approach proposed by L. Tan and co‐workers in their Communication on page 1887 ff. The stability of carbon‐centered bioorganic radicals is evaluated by a method based on the gas‐phase dissociation of sulfinyl radical ions. The degree of CH 2 SO loss is found to be correlated with the stability of the as‐formed radical species, which can be molecularly tuned by the electronic effect of the neighboring groups.
