For a hydrogen atom with n =1, the electron is in its ground state; if the electron is in the n =2 orbital, it is in an excited state. The total number of orbitals for a given n value is n2. Angular Momentum (Secondary, Azimunthal) Quantum Number (l): l = 0, ..., n-1. Specifies the shape of an orbital with a particular principal quantum number.
Spin is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum. The orbital angular momentum operator is the quantum-mechanical counterpart to the classical notion of angular momentum: it arises when a particle executes a rotating or twisting trajectory (such as when an electron orbits a nucleus).
Electrons are spin-1 ⁄ 2 particles. These have only two possible spin angular momentum values measured along any axis, + or, a purely quantum mechanical phenomenon.Because its value is always the same, it is regarded as an intrinsic property of electrons, and is sometimes known as "intrinsic angular momentum" (to distinguish it from orbital angular momentum, which can vary and depends …

Core levels in XPS use the nomenclature nl j where n is the principal quantum number, l is the angular momentum quantum number and j = l + s (where s is the spin angular momentum number and can be ±½). All orbital levels except the s levels (l = 0) give rise to a doublet with the two possible states having different binding energies.This is known as spin-orbit splitting (or j-j coupling)[1].
