    • It should be noted that differences in the mass analyzers and CID conditions used in this study had a significant impact on their respective ESI-MS/MS spectra. In particular, preliminary MS/MS analyses using the ion trap mass analyzer were performed with a cutoff at 30% of the parent ion m/z ratio; therefore, no ions below this threshold could be observed

    • Isotopic parent ion peaks were observed in the MS/MS spectra of 4b, 7b, and 6b. These were higher than expected after CID, possibly due to perturbations in rf resonance frequencies corresponding with the expected parent ions.
