Upon electron impact, 4,4-dimethyl-5α-androstan-3-one decomposes into two major fragment ions appearing in the mass spectrum at m/e 175 and 216. From the spectra of several deuterated analogs of the parent ketone, both ions were shown to be hydrocarbon fragments resulting from extremely complex processes which are not susceptible to ready interpretation by the conventional principles of physical-organic
