To distinguish between the canonical EOM-EE-CCSD and fc-CVS-EOM-EE-CCSD methods, we use different symbols below. The calligraphic symbols, H, T , L, R, E, X , and G, are associated with the canonical EOM-EE-CCSD method and regular symbols, H, T , L, R, E, X, and G, are associated with the fc-CVS-EOM-EE-CCSD method.
