WebRacah & Paschen notation The following two tables can be used to translate Paschen notation into Racah notation and vice versa. Orbital Block s 4s 5s 6s 7s In atomic physics, a term symbol is an abbreviated description of the total spin and orbital angular momentum quantum numbers of the electrons in a multi-electron atom. So while the word symbol suggests otherwise, is represents an actual value of a physical quantity. For a given electron configuration of … See more The usual atomic term symbols assume LS coupling (also known as Russell–Saunders coupling), in which the atom's total spin quantum number S and the total orbital angular momentum quantum number L are " See more It is relatively easy to calculate the term symbol for the ground state of an atom using Hund's rules. It corresponds with a state with maximum S and L. 1. Start with the most stable electron configuration. Full shells and subshells do not contribute to … See more Basic concepts for all coupling schemes: • $${\displaystyle {\boldsymbol {\ell }}}$$: individual orbital angular momentum vector for an electron, $${\displaystyle \mathbf {s} }$$: individual spin vector for an electron, $${\displaystyle \mathbf {j} }$$: individual total … See more • Quantum number • Angular quantum numbers • Angular momentum coupling • Molecular term symbol • Hole formalism See more For a given electron configuration, • The combination of an $${\displaystyle S}$$ value and an $${\displaystyle L}$$ value is called a term, and has a statistical weight (i.e., number of possible states) equal to $${\displaystyle (2S+1)(2L+1)}$$; • A combination of See more The process to calculate all possible term symbols for a given electron configuration is somewhat longer. • First, the total number of possible states N is calculated for a given electron configuration. As before, the filled (sub)shells are … See more These are notations for describing states of singly excited atoms, especially noble gas atoms. Racah notation is basically a combination of LS or Russell–Saunders coupling and J1L2 coupling. LS coupling is for a parent ion and J1L2 coupling is for a coupling of the … See more
