MP2SS reduces finite-size errors in periodic MP2 to millihartree accuracy at coarser k-point meshes for gapped systems via auxiliary function subtraction.
BN doping renders the planar-to-Dewar isomerization asymmetric via a B-C stabilized metastable intermediate whose transition state resembles an S0/S1 conical intersection, and targeted substitution red-shifts S1 while boosting oscillator strength and Dewar yield.
Crystal-field tensor rank in non-magnetic molecular solids sets selection rules for nuclear-spin conversion of embedded H2, demonstrated via IR spectra showing rank-dependent Delta-m channels in CO2, N2O, and NO2 hosts.
Orbital-optimized DFT with plane waves yields useful absorption intensities for single-configuration Rydberg states but fails for multi-configurational states, with median errors of ~29% vs ~189%.
Plane-wave orbital-optimized DFT gives reliable dipole moments for diffuse Rydberg states where atom-centered basis sets fail, and PBE0 is the best functional tested.
Experimental synthesis of phosphorus-doped triangulene superatomic graphene exhibiting tunable flat bands and half-metallic magnetism via oxygen functionalization.
Experiments identify acenaphthene derivatives from C11H9+ reactivity with methylated naphthalenes and link them to efficient formation of acenaphthylene-like species in cold clouds.
New gas-phase measurements of C 1s binding energies in anthrone agree with ΔSCF calculations, and a benchmark of 44 core levels in molecules with 10-40 atoms yields a mean absolute error of 0.19 eV.
A finite-displacement phonon workflow for MOF-5 demonstrates that spurious imaginary modes can be eliminated by tighter force/grid convergence and careful cell/symmetry choice, with a residual soft A2g mode mapping to a shallow Fm-3 displacive minimum.
Orbital-optimized DFT is surveyed as a variational, state-specific alternative to TDDFT for balanced treatment of diverse molecular electronic excitations.
