It is a mathematical property of spherical harmonic functions Yem(6, ) that they obey an addition rule which is known as the biaxial theorem if ri and r2 are two vectors, with directions described by the polar angles (6i, 4> ) and (62,4>2), and if a is the included angle between the two vectors, then...
