OrbToMultiplicity

OrbToMultiplicity(orb) tries to interpret the string orb as an atomic orbital and returns the multiplicity of the state (spin included).

Input

  • orb : String that can be interpreted as an atomic orbital (i.e. orb ends on “s”, “p”, “12”, “32”, “1/2”, “3/2”, or the like)

Output

  • mult : Interger value of the multiplicity of the orbital
