B97-type power-series expansions for both exchange and correlation have become important for many literature functionals, 26,65-67 starting with Becke's original work. The essential initial idea has been to attempt to generate as flexible GGA functionals as possible. Later adaptations extended the B97c correlation functional to a meta-GGA framework by adding self-correlation corrections. Our focus here is just on B97c-type correlation with such self-correlation corrections only for the same-spin part (employing α σ (r) as in B95c, cf. eq. 5) as a more flexible alternative to B95c used so far. We thus consider a correlation-energy density of the form e B97c (r) = e opp B97c (r) + σ e σσ B97c (r) ( )
