The spherical harmonics have deep and consequential properties under the operations of spatial inversion (parity) and rotation. The spherical harmonics have definite parity. That is, they are either even or odd with respect to inversion about the origin. Inversion is represented by the operator . Then, as can be seen in many ways (perhaps most simply from the H…
