Functional systems with orthogonal dynamic covalent bonds.

This review summarizes the use of orthogonal dynamic covalent bonds to build functional systems. Dynamic covalent bonds are unique because of their dual nature. They can be as labile as non-covalent interactions or as permanent as covalent bonds, depending on conditions. Examples from nature, reaching from the role of disulfides in protein folding to thioester exchange in polyketide biosynthesi...

Chemical Bonding: The Orthogonal Valence-Bond View

Chemical bonding is the stabilization of a molecular system by charge- and spin-reorganization processes in chemical reactions. These processes are said to be local, because the number of atoms involved is very small. With multi-configurational self-consistent field (MCSCF) wave functions, these processes can be calculated, but the local information is hidden by the delocalized molecular orbita...

Formation of Semi - Covalent Bond in [ (

IR photodissociation (IRPD) spectra of [(N2O)nH2O] with n = 2–7 are measured in the 1100–3800 cm region. In parallel, the geometry optimization and the vibrational analysis are carried out at the B3LYP/6-311++G(d,p) level of theory. In the OH stretching (2400–3800 cm) region, the IRPD spectrum of the [(N2O)2H2O] ion shows a sharp band at 3452 cm and a broad one at around 2700 cm, which are assi...
