Notes:
The major fragmentation pathways of eight isomeric androstane-3,17-diols, as their bis-t-butyldimethylsilyl ethers, were elucidated by linked scanning of the magnetic and electric fields in a double focusing mass spectrometer. Four competing pathways were observed, each characterized by losses of alkylsilanol moieties from a common [M-C4H9]+ precursor. Pronounced differences in the spectra obtained by linked scans complement the coventional mas spectra in the differentiation of the isomeric structures.
