## 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
In the course of studies of A5-3P-hydroxy steroids in human urine, the absorption spectra of these compounds in two sulfuric acid reagents proved of value in arriving at their identification (1). Wilson (2) has previously reported spectra of 11 steroids in sulfuric acid reagents. Smith et al. ( 3) h
