Dialkylaminostyryl probes with two long alkyl chains were used to investigate the energetics of charge-remote fragmentation (CRF). These compounds provide high-quality liquid secondary ion (LSI) and electrospray ionization (ESI) mass spectra in which the intact cation predominates. The intact cation
The collisional activation spectra of lithiated and bariated cations and deprotonated anions of the triterpenoic acids hederagenin and oleanoic acid and their acetyl derivatives were examined. On collisional activation these precursors undergo similar charge-remote fragmentations including ring clea
## Abstract A series of alkyltrimethylammonium cations, generated by fast atom bombardment from 1‐dodecanaminium‐, 1‐tetradecanaminium‐ and 1‐hexadecanaminium‐__N__,__N__,__N__‐trimethyl bromides, were studied by high‐energy collisions and comparison with __N__,__N__,__N__‐trimethyl‐__d__~9~ labell
