LCAO-SCF calculations of various types have been performed for 3-hydroxy-isothiazole and related species. A perturbation analysis has shown that the values assigned to some of the semi-empirical parameters affect the results to a greater extent than has been supposed. Some of the chemical properties can be rationalized on the basis of these calculations.
