    “…A triplet ground state is predicted for this hydrocarbon by Ovchinnikov's rule, or Lieb's theorem, in accord with Hund's rule. The pioneering work on triangulene was performed almost 70 years ago by Erich Clar, who attempted to prepare the pristine compound. …”

    “…In the next three electron transfer steps, as the adsorbed O species adopt fixed spin direction, the OER electrons need to follow the Hund rule and Pauling exclusion principle, thus to carry out spin polarization spontaneously and finally lead to the generation of triplet state O(2). …”

    “…[Image: see text] The new generation of proposed light-emitting molecules for organic light-emitting diodes (OLEDs) has raised considerable research interest due to its exceptional feature—a negative singlet–triplet (ST) gap violating Hund’s multiplicity rule in the excited S(1) and T(1) states. …”

    “…FeMoco and an analogous small‐molecule (Et(4)N)[(Tp)MoFe(3)S(4)Cl(3)] cubane have both been proposed to contain unusual spin‐coupled Mo(III) sites with an S(Mo)=1/2 non‐Hund configuration at the Mo atom. Herein, we present Fe and Mo L(3)‐edge X‐ray magnetic circular dichroism (XMCD) spectroscopy of the (Et(4)N)[(Tp)MoFe(3)S(4)Cl(3)] cubane and Fe L(2,3)‐edge XMCD spectroscopy of the MoFe protein (containing both FeMoco and the 8Fe‐7S P‐cluster active sites). …”

    “…Accordingly, significant (P < 0.005) variations were observed among the species in shoot height, collar diameter, height to collar diameter ratio, number of leaves and seedling survival. Acacia origena Hunde, A. gerrardii Benth., and A. johnwoodii Boulos. were superior over the others in most parameters while A. etbaica Schiweinf. and A. asak (Forssk.) willd. were less vulnerable to chanced pathogens. …”

    “…For a d(2) electron configuration of the N≡MF(3) compounds in C (3v) symmetry, Hund's rule predict a high‐spin (3)A(2) ground state with two parallel spin electrons and two degenerate metal d(δ)‐orbitals. …”
