Some of the constraints on models of Type I supernovae which can be inferred from the observations are discussed. Comparison of McDonald Observatory spectra of the SN I of 1981 in NGC 4536 establishes that elements other than nickel, iron, and cobalt are represented in the maximum-light spectrum, and that permitted Fe II lines are present 17 days later. For models which power the light-curve peak by radioactivity, the lower limits on the mass of ejected nickel are discussed. The rate of decline of the post-peak light curve appears to be correlated with expansion velocity and absolute magnitude. If these correlations can be firmly established they will provide stringent tests of SN I models.
