Proton Transfer Mass Spectrometry of Underivatized Peptides? Robert J . Beuhler, Everett Flanigan, Lewis J . Greene, and Lewis Friedman*

A B S T R A C I . Proton transfer spectra of the following under]vatited peptides have been studied in a tandem mass spectrometer system: Ser-Phe-Pro, Met-Val-His, Leu-Trp-Met, Met-Met-Leu. Tyr-[le-His-Pro-Phe, Gly-Phe-Ser-Pro-Phe, Phe-,4sp-Ala-Ser-Val, Asp-Ser-Leu-Gly-Arg,
