## Abstract The PE spectra of the 4,5‐dihydro‐3__H__‐pyrazoles 1, 2, of 2,5‐dihydro‐1,3,4‐oxadiazole 3, and 2,5‐dihydro‐1,3,4‐thiadiazole 4 have been recorded. Based on HAM/3, MNDO, AM1, and PM3 calculations, the ionization potentials have been assigned to molecular orbitals. The gas‐phase thermoly
