This Letter is concerned with formalism for performing spin-dependent CI calculations on molecules, We communicate the mathematical formulae for the matrix elements of the U (2n) generators in the spin-orbit U(n) xU( ) symmetry adapted basis, as required for spin-dependent (CI) calculations. Our for
The relations between the masses in a unitary multiplet are derived from the c-and I-spin properties of the mass splitting interactions. IVarious simple rules --the Parallelogram Law and the nth Difference Rule-are derived. It is shown that the Gell-Mann-Okubo formula is just an equal spacing rule f
The matrix elements of spin-dependent U (2n) generators are given explicitly. These matrix elements are expressed in terms of those of spin-independent U(n) and U (n + 1) generators, and can therefore be easily incorporated into existing unitary group approach based programs.
