Complete high resolution mass spectra of several analogs of the juvenile hormones have been analyzed with the aid of our recently developed INTSUM program and mass spectra of deuterated analogs. Representative compounds chosen for study included the biologically interesting (2E, 4E)‐3,7,11‐trimethyl‐2,4‐dodecadienoates (1,2), (2E,4E)‐11‐methoxy‐3,7,‐11‐trimethyl‐2,4‐do‐decadienoates (3,4) and three analogs (5‐7) of the trans‐trans‐farnesoate skeleton. These compounds display characteristic fragmentations which can be used to detect the presence of the compounds in complex mixtures using mass fragmentography or aid in the structure elucidation of related compounds.
