Term symbols usually specify the total for all electrons in an atom, but are sometimes used to describe electrons in a given subshell or set of subshells, for example to describe each open subshell in an atom having more than one. The ground state term symbol for neutral atoms is described, in most cases, by Hund's rules.
Term symbols are used to represent the states and spectral transitions of atoms, they are found from coupling of angular momenta mentioned above. When the state of an atom has been specified with a term symbol, the allowed transitions can be found through selection rules by considering which transitions would conserve angular momentum .
Henry Norris Russell ForMemRS HFRSE FRAS (October 25, 1877 – February 18, 1957) was an American astronomer who, along with Ejnar Hertzsprung, developed the Hertzsprung–Russell diagram (1910). In 1923, working with Frederick Saunders , he developed Russell–Saunders coupling, which is also known as LS coupling .
This notation is used to specify electron configurations and to create the term symbol for the electron states in a multi-electron atom. When writing a term symbol, the above scheme for a single electron's orbital quantum number is applied to the total orbital angular momentum associated to an electron state. [4]

Russell Maurice Saunders (May 21, 1919 – May 29, 2001) was a stunt man and acrobat. Saunders did Alan Ladd's fight scene in Shane. He also doubled for Gene Kelly in Singin' in the Rain and An American in Paris. [1] He was in many other famous movies from as early as Hitchcock's Saboteur in 1942 to as late as Mississippi Burning in 1988.
