text: The LUMO energies behave unusually in a sequence O, S, and Se: their mean values for oxadiazolo[3,4-c]pyridine and selenadiazolo[3,4-c]pyridine derivatives are statistically comparable but substantially lower than that for thiadiazolo[3,4-c]pyridine derivatives (Table 2) that should provide a red shift in the UV-Vis spectra for O and Se containing π-blocks.
