Notes:
The mechanism of water elimination from metastable molecular, [M - CH3·]+ and [M - ring D]+· ions of epimeric 3-hydroxy steroids of the 5α-series has been elucidated. Deuterium labelling, the measurement of the translational energy released during the loss of water, and collision-induced decomposition mass-analysed kinetic energy spectrometry were the techniques used. It was found that the mechanisms of water loss from metastable M+· and [M - ring D]+· ions is different from that from [M - CH3·]+ ions.
