Theoretical and experimentally determined deconvoluted (4z) masses for α 2–6. The 4z ion was chosen since it falls within the calibrated mass range for the QToF used. All values for 2–6 are within 10 ppm of the expected masses.

For 7, only low-resolution MS (LCQ deca) was available; the convoluted mass was calculated for the doubly charged average mass ion.
