Abstract The mass spectra of 4,4′‐oxybispyridine and 4,4′‐thiobispyridine are reported. In the former the base peak is due to the molecular ion and the fragmentation routes involve loss of H, CO, HCN, C 2 H 2 N and C s HO from the molecular ion as well as rupture of the central bonds. In the latter the base peak is also due to the molecular ion and the fragmentation routes involve loss of H, CS, S, HCN and C 2 HS as well as central bond rupture.
