The Harvard noncoplanar geometry is used to specify calculations of the different and integrated cross sections and of the component analyzing powers from [ital pp] bremsstrahlung. This geometry is equivalent to spherical polar coordinates for coplanar scattering. A wide range of incident energies and symmetric proton emission angles are considered in studying various properties of the reaction. Emphasis is placed on an energy of 280 MeV and for forward proton angles, at which results are most sensitive to specific off-of-the-energy-shell properties of the two nucleon [ital t] matrices. Those [ital t] matrices are generated with various interactions. The importance of the [ital NN] [ital t]-matrix off-diagonal tensor contributions for the coplanar observables as demonstrated in the pioneering work of Brown is clearly shown. Photon cross sections vary with the noncoplanarity of the reaction due in part to changes in relative importance of diverse [ital NN] channel [ital t] matrices. The analyzing powers likewise vary with azimuthal angle and reveal a particular sensitivity to the tensor coupled [sup 3][ital P][sub 2-][sup 3][ital F][sub 2] channels and to the [sup 3][ital P][sub 0] channel.
