The spectrum of the conformal Dirac operator on the n-sphere is used to obtain sharp L^2 inequalities for this operator and several related operators including the conformal Laplacian and Paenitz operator. Stereographic projections are used to obtain similar inequalities in R^n. This spectrum is also used to explain the break down of related sharp inequalities in even dimensions including sharp inequalities for the bi-Laplacian in four dimensions.
