Explicitly correlated electronic structure theory from R12/F12 ansätze (2012, background): “Toward More General CC-F12 Ansatz A great (theoretical and computational) advantage of the CC ansatz using excitation operators T̂n′ of Eqs (28) and/or (29) together with the ‘conventional’ excitation operators T̂n is hidden in the fact that all operators in the exponential mutually commute.”
Transient reducing greenhouse warming on early Mars (2016, neutral): “…of our CIA and line-by-line climate calculations are given in the supporting information [ Cherepanov et al. , 2016; Boys and Bernardi , 1970; Knizia et al. , 2009; Cohen and Roothaan , 1965; Clough et al. , 1992; Rothman et al. , 2013; Murphy and Koop , 2005; Gruszka and Borysow , 1997;…”
Quest for a universal density functional: the accuracy of density functionals across a broad spectrum of databases in chemistry and physics (2012, methodology): “ the original IsoL22 are questionable, we recently [94] recalculated the reference energy for six of the smallest molecules in Grimme’s database by using the accurate CCSD(T)- F12a/aug-cc-pVDZ method [132, 133, 134, 135, 136], and collect the results in the IsoL6/11 set. Geometries for this set are ”
