Notes:
Secondary isotope effects were examined in the loss of methyl from the molecular ions of C2D5OC2H5 and CD3CH2OC2H5 for ion source processes and collisional activation (CA) processes. In the ion source loss of CH3 was slightly favored over loss of CD3, but in CA the CH3 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.
