Resumen:
The recently published results of a theoretical calculation of thephysicochemical properties of acenaphtho[1,2-c]- and phenanthro[9,10-c]-1,2,5-thiadiazole 1,1-dioxide, using a modified density functional theory (CHIH-DFT), arecompared with our experimental results. The CHIH-DFT-calculated IR spectra of bothcompounds are also compared with those obtained using relatively simple RHFcalculations. It is concluded that, in these cases, the improvements claimed for the newmodel chemistry are marginal. The IR spectra of three new derivatives of 1,2,5-thiadiazole are also reported and calculated.
