The ratios ( A ) of metas table‐ and parent‐ion peak heights measured by me testable defocusing and the B / E inked scan technique have the same order of magnitude. This was established for the M + → [M ‐ 15] + and M + → [M − OR 1 ] + (R 1 = 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.
