✦ Synopsis

Secondary isotope effects were examined in the loss of methyl from the molecular ions of C,D,OC,H, and CD,CH,OC,H, for ion source processes and collisional activation (CA) processes. In the ion source loss of CH, was slightly favored over loss of CD, , but in CA the CH, loss was favored to a much larger extent than expected. A possible explanation is given which invokes an energy distribution function peaked near the appearance energy for the methyl loss process.
