The sum of the mass spectral line intensities m/e 87 and 86 was always greater than 30 000 counts. if 2 is an intermediate (“[2+ 2+ 2]”), 0: 2: 1 if the rearrangement involves 4b and 5 (but not 7)(“[3.3]”), and 2: 6: 7 if 7 is readily accessible (“spir0 [3.3]”).*~ Should there somehow be scrambling of the label ...
