Abstract: We consider spinors carrying a representation of the Clifford algebra generated by a complex 2r-dimensional vector space V. Certain spinors, called pure, admit a remarkable geometrical interpretation since they may be placed in correspondence with maximal totally isotropic subspaces of dimension r. This correspondence has allowed the orbit structure of pure spinors under the action of the Spin group to be classified. An `impure' spinor u may be put into correspondence with an isotropic subspace of dimension n < r. Except for low dimensions, the classification of the impure spinor orbits is incomplete. In the first part of the thesis, we present a coarse classification of impure spinors based on (1) the value of n and (2) the decomposition of u into pure components.

In later chapters we examine certain equations for spinor fields on manifolds. On spacetime, we show that the conformal Killing equation for a null vector field is equivalent to a generalisation of the twistor equation. From it we derive Sommers' equation for a spinor corresponding to a null shear-free geodesic. We also find equations for a Dirac spinor equivalent to the conformal Killing and shear-free conditions for a timelike vector field.

Finally, it is shown that a pair of shear-free Weyl spinors may be used to construct a 2-form satisfying a generalised conformal Killing-Yano equation. Via spinors, the conformal Killing-Yano 2-form is used to construct symmetry operators for the massless Dirac equation and the vacuum Maxwell equation. In the case of the Dirac equation, we are able to construct a symmetry operator from a conformal Killing-Yano tensor of any degree in arbitrary dimensions.
