## Abstract The 70 eV negative ion mass spectra of some simple aromatic and aliphatic thio and dithio esters are discussed. A characteristic fragmentation process, a rearrangement analogous to the nitro‐nitrite conversion of aromatic nitro compounds, is observed for aromatic thio esters.

## Abstract 70 eV positive and negative ion mass spectra of a series of copper(II) Schiff base complexes have been obtained consecutively under the same ion source conditions. The characteristic feature of the negative ion spectra is their extreme simplicity relative to the corresponding positive i
## Abstract Electron capture by and the subsequent fragmentation of a series of eleven fluorinated β‐diketones of general formula CF~3~COCH~2~COR has been studied in an MS‐50 mass spectrometer. Consecutive loss of two HF molecules from molecular anions occurs with all compounds, as does elimination
