Studies of both high and low resolution spectra, and of metastable decompositions occurring in both the first and second field‐free regions of the mass spectrometer have led to a postulated scheme for the fragmentation of acridine under electron‐impact. There is no specific loss of label from either [9‐ 2 H 1 ]acridine or [4,5‐ 2 H 2 ]acridine in any fragmentation, nor is there any total scrambling of label in either molecular ion prior to loss of HCN. There is certainly some degree of scrambling preceding HCN loss from [M] + ˙ at 70 eV, but this does not involve the 9‐H to any detectable extent. There is no strong evidence for the acridine molecular ion having the same structure as that of four other C 13 H 9 N isomers.
