We can use either of these forms to determine that each of the carbon atoms is bonded to three other atoms with no lone pairs, so the correct hybridization is sp2. The electrons in the unhybridized p orbitals form ππ bonds. Neither resonance structure completely describes the electrons in ...
These diene polymers or copolymers are prepared by a method which involves first terminating substantially all of the living diene polymer or copolymer chains obtained by anionic polymerization with a compound having multiple-bonded nitrogen atoms selected from the group consisting of aromatic nitriles ...
48). This could be explained by the nature of polarization-driven halogen···halogen contacts, where more polarized iodine···iodine interactions tend to be favored compared to halogen bonds involving bromine or chlorine atoms60. The I2 adsorption capacity from n-hexane solution by 3·6I ...
Non-phosphorus-bound hydrogen atoms are omitted for clarity. The Th Á Á Á HP agostic-type interaction suggested by the structural, NMR and IR spectroscopic data is omitted for clarity. where the terminal PH2 unit resides trans to the Tren-amine centre (N4–Th1–P1 ¼ 174.10(15)°...
two R51's attached to different atoms, together with the atoms to which they are attached, form a substituted or unsubstituted C3-C10 carbocycle, substituted or unsubstituted heterocycle comprising one or two 5- or 6-member rings and 1-4 heteroatoms selected from N, O, and S, or substitute...
Before transfer printing materials, the team developed a method to assemble multiple devices on a single chip that allowed it to place the multiple devices very close together without affecting the devices already present on the chip. Researchers at the University of Strathclyde developed a way assem...
The nitrogen donor atoms of the bpy ligand in 35 clearly do not contain any hydrogens, in contrast to conventional platinum(II)-DNA binding agents, which typically contain primary or secondary amine donor ligands in which the hydrogens are thought to be important for hydrogen-bonding interactions...
to differentiate N and O which have respective neutron scattering lengths of 9.36 and 5.83 fm (Table1) in oxynitrides. Neutron scattering also enables the positions of these light atoms to be determined more precisely in the presence of heavy metal atoms than is usually possible from X-ray...
Agglomerated submerged arc welding flux is susceptible to moisture pick-up. This is because agglomerated flux consists of small particles that are bonded together, leaving spaces between them where moisture can be trapped. Moisture in the flux can lead to porosity and other defects in the weld, ...
The operation was repeated with no fixed atoms. The final structure was checked for poor φ, ψ, and ω angles and residues of high energy. The loops used in the model are detailed as follows. Domain 1: A/B, (EDS) modeled to GDT from 2cd4 (designated loop); B/C loop (SPESD) ...
