Six structurally related crown ethers have been studied by electron impact @I) mass spectrometry. From accurate mass measurements, metastabel ion and mass-analyzed ion kinetic energy (MIKE) spectra, plausible fragmentation pathways were deduced. All compounds showed very abundant molecular ions and

## Abstract The mass spectra of pyridyl‐18‐crown‐6 and pyridyl‐15‐crown‐5 were determined. The spectra of five deuterium labeled analogues of pyridyl‐18‐crown‐6 coupled with high resolution data, allowed formulation of fragmentation pathways, which are dominated by several series involving the loss

Extensive networks of metastable ions link the major peaks in the electron impact mass spectra of two crown ethers containing 2,6-pyrido units. High-resolution mass measurements and the metastable peaks allow the elucidation of the fragmentation pathways. The spectra are influenced more by the prese
