In MSMS, the different collision energies used to obtain the product ion spectra [daughter ion spectra in 20th century terminology] can have dramatic effects on the spectra. This video gives a quick look at the product ion spectra of a dipeptide (Val-Ser) at 4 different collision energies. Initial ionization was via electrospray. ... Pdf data files for 5 dipeptides [Ala-Gly; Ala-Ser; Ser-Ala; Val-Leu; Val-Ser ]and 1 tripeptide [Val-Leu_Ser] are available for download. Data includes spectra with a very broad range of collision energies.
