Abstract

A systematic study of 1, 2, 5-Thiadiazole (I), 2, 1, 3-Benzothiadiazole (II) and the recently synthesised Naphtho[2, 3-c]-1, 2, 5 thiadiazole (III) has been made using the Huckel molecular orbital theory (HMO). Stability and reactivity of these molecules as predicted by HMO calculations are in agreement with experimental observations. For (I) and (II) bond lengths are known and excellent agreement with theory has been shown. Spin densities calculated for the radical anion of (II) are in good agreement with experimental data. Bond lengths in (III) and its reactivity as well as the spin densities for its radical anion are predicted.
