The chemistry of nitric oxide (NO) has taken on new dimensions since the discovery, about a decade ago, of a myriad of biological events that NO participates in. Many of the foundations of metal-NO chemistry were laid out earlier by inorganic chemists and biochemists investigating the structures and electronic properties of the heme-NO moiety or its model compounds. Certainly, the persistent work over the last three decades by chemists working with metal nitrosyls has paid off. Current areas of research in heme-NO chemistry include (i) how the NO group approaches and binds to the metal center (or how it dissociates from the metal center); (ii) the ground state and excited state geometries of the metal-NOfragment; (iii) effects of the trans axial ligands on NO orientation and/or dissociation; and (iv) N-N bond formation from NO molecules catalyzed by heme groups.

Intra- vs. intermolecular hydrogen-bond formation and ESIPT in a bioactive flavonoid result in different emission properties and provide a clue for recognizing its binding to target proteins.

<div><p>In this work, the 2s+2s (face-to-face) prototypical example of a photochemical reaction has been re-examined to characterize the evolution of chemical bonding. The analysis of the electron localization function (as an indirect measure of the Pauli principle) along the minimum energy path provides strong evidence in support that CC bond formation occurs not in the excited state but at the ground electronic state after crossing the rhombohedral S<sub>1</sub>/S<sub>0</sub> conical intersection. </p></div><br>
