## Abstract An ion formed by loss of 56 mass units from the molecular ion is often seen in mass spectra of trimethylsilyl ethers of C~19~ and C~21~ steroids having a 3β‐hydroxy‐Δ^5^ structure and an oxo group at C‐17 or C‐20. The nature of this fragment was investigated by the use of perdeuteriotri
