A mass spectrometric investigation at 70 eV and at low voltage of specifically deuterated and undeuterated 2,4‐dimethyl‐1‐pentene is reported, in order to illustrate the specificity of the degradation reactions occurring under electron‐impact. A mechanism for the skeletal rearrangement of the molecular ion prior to fragmentation is proposed.
