Partial mass spectra of 1α, 2β-, 2α, 3β-, 3α, 4β-, 3β, 4α-, 4β, 5α-, 5α, 6β- and 6β, 7α-dihalocholestanes and -halocholestanols are given. Applicability of mass spectrometry for structure determination of these compounds types is demonstrated. Although the differences found in the appearance of their mass spectra are often only quantitative, they are characteristic enough for reliable localization of the substitution.
