The mass spectra of fragments of some steroids and triterpenoids produced by bombardment with electrons of 9 to 15 ev energy indicate thermal fission during introduction of the molecules into the ion chamber. The scope and limitations of this technique are discussed, particularly for the determination of the length of the side-cchnin. Experiments with 30 to 70 ev electrons permit study of dissociations induced by electron impact and the spectra of cholestane, ergostane, lanost-9(11)ene, and stigzmastadiene fragments have been qualitatively interpreted.
