WebJun 15, 2024 · The spherical harmonics are a set of special functions defined on the surface of a sphere that originate in the solution to Laplace's equation, $\nabla^2f=0$. Because they are basis functions for irreducible representations of SO(3), the group of rotations in three dimensions, they appear in many scientific domains, in particular as the angular part of … WebIt is common to see the opposite convention, that is, theta as the polar angle and phi as the azimuthal angle. Note that SciPy’s spherical harmonics include the Condon-Shortley phase [2] because it is part of lpmv. With SciPy’s conventions, the first several spherical harmonics are.
