Fig. 7. ESI-MS3 spectra of dehydrated PVP and P(VP-co-VSI) 3-mers at m/z 376.2 (VP3), m/z 390.2 (VP2VSI1) and m/z 404.2 (VP1VSI2) formed upon the release of water from the protonated (co-)oligomers. Asterisks designate the product ions formed upon the loss of 58.0 Da neutral (proposed to be C3H6O) from the 2-hydroxyisopropyl termination.
