Notes:
The mass spectra (20 eV electron energy) of a wide range of %Δ5-3β-hydroxy C19 steroid TMS ethers have been examined with the aid of high-resolution mass measurements, together with deuterium and oxygen-18 labelling data. The validity of many previously proposed fragmentation modes has been confirmed. A number of ions regarded as diagnostic have been shown to be less specific than had been formerly supposed. Several novel fragmentations have been observed and investigated.
