[M + Ag] + ions from cyclic and linear polystyrenes and polybutadienes, formed by matrix-assisted laser desorption ionization (MALDI), give rise to significantly different fragmentation patterns in tandem mass spectrometry (MS 2 ) experiments. In both cases, fragmentation starts with homolytic cleav...
