Cover Story: An improved approach to obtaining reliable NMR spectroscopic parameters for platinum complexes is presented. By developing and validating an AMBER force field for such complexes conjugated with AHBT, molecular dynamics simulations were carried out in enzymatic and aqueous environments, and strategies to select the best amino acid residues and water molecules were proposed. The results obtained show that this methodology allows for the acquisition of more reliable chemical shifts and spectroscopic probes, with significant differences observed between these two surroundings. View this paper

Zero-Field Splitting in Hexacoordinate Co(II) Complexes

  • Roman Boča,
  • Cyril Rajnák and
  • Ján Titiš

A collection of 24 hexacoordinate Co(II) complexes was investigated by ab initio CASSCF + NEVPT2 + SOC calculations. In addition to the energies of spin–orbit multiplets (Kramers doublets, KD) their composition of the spins is also analyzed, al...

  • Anastasiia D. Molchanova,
  • Alexey R. Nurmukhametov,
  • Mikhail V. Eremin,
  • Roman V. Pisarev and
  • Marina N. Popova

The change in the absorption spectra due to reversal of the direction of light propagation (nonreciprocity of absorption) is a consequence of a simultaneous violation of both time-reversal and spatial-inversion symmetries. Here, we report on a high-r...
