| Abstract: | The fragmentation reaction C3(H,D)6]+· → C3(H,D)5]+ + (H, D) has been examined in the metastable decomposition region for two pairs of labelled propenes: CH3CD?CH2,CD3CH?CD2 and CD3CH?CH2, CH3CD?CD2. The results indicate that complete hydrogen scrambling occurs in the propene molecular ion prior to fragmentation. The isotope effect kH/kD is in the range 2·1 to 3·3. |
