Note on the P-basis mentioned by Shankar : 

 

In solving the one-dimensional Schrödinger equation, the potential V(x) is usually a more complicated function of x than the kinetic energy is of p. The position and momentum obey the commutation relation , and the standard approach is to write   However, we could equally write   the commutation relations are satisfied, and writing the Hamiltonian in terms of leads to a differential equation whose solution is the p-space representation (the Fourier transform) of the usual y(x). This is occasionally the best strategy—in particular, for a particle in a linear potential.
