✦ Synopsis
The ratios ( A ) of metastable-and parent-ion peak heights measured by metastable defocusing and the B/E linked scan technique have the same order of magnitude. This was established for the M+ + [M -151' and M+ + [M -OR'] + (R' = H, Me, Ac) transitions in the mass spectra of diterpene alkaloids with a licoctonine skeleton. The A values were demonstrated to depend on the position of the eliminated group in the parent molecule.
The A values can also be employed as a criterion for the identification of daughter-ion reaction configurations.
