## Abstract The Electrospray Mass Spectrometry (ESβMS) of eight different supramolecular complexes shows that the molecular peaks of the desolvated multiply charged cations can be recorded more easily than by FastβAtomβBomβbardment Mass Spectrometry (FABβMS) measurements of similar compound. The pr
Electrospray ionization (ESI) was used in conjunction with quadrupole ion trap mass spectrometry to measure metal binding selectivities of bis-crowned clefts in methanol solution. Each of the three cleft compounds contained two 15-crown-5 rings separated by di β erent quinoline spacers. Binding selec
The liquid secondary ionization mass spectra of crown ether solutions and crown ether solutions containing alkali metal cations were generated. Cesium cations acted as both the primary ion beam and as a competing gas-selvedge-phase reactant. The data suggest that crown ether complexes formed in the
