The first-order wave function terms which result from linear R12 terms are: Fij (1) = Ckl ij ( r12 |kl> - 0.5 rab kl |ab> - 0.5 rmn kl |mn> - ram kl |am> - ra'm kl |a'm> ) where C are optimal first-order coefficients and r are antisymmetrized integrals over r12 operator. Indices a, b are virtual MOs; m,n are occupied MOs; i, j, k, l are active occupied MOs, a' is an RI basis index. Author Generated automatically by Doxygen for MPQC from the source code.
