benzene ring

n.
A hexagonal ring arrangement found in benzene and other aromatic compounds, consisting of six carbon atoms with alternating single and double bonds between them, and with each carbon atom bonded to a hydrogen atom, or to other atoms or groups of atoms in derivatives of benzene.

The 1H-NMR spectrum (Table-1) of 1 afforded four signals in the aromatic region at I' 7.33 (2H, d, J = 8.4 Hz), 7.32 (2H, d, J = 8.4 Hz), 7.10 (2H, d, J = 8.4 Hz) and 7.08 (2H, d, J = 8.4 Hz), which depicted two p-substituted benzene rings in the molecule.
This ligand is tricarboxylate and possess two benzene rings connected via oxygen atom, the two benzene rings can rotate freely around -O-groups with different angles to meet the requirement of the coordination geometries.
And compare two diamines; TPER polyimides have ether bond between the benzene rings, which are a weakness to thermal stability, so their weight loss temperatures are lower.
The reference wavenumber is 1,600 [cm.sub.-1] since this shows the polymerization of benzene rings. The "hill" portions of the piston top refer to positions (3) and (4) from Fig.
These are alkanes (saturated hydrocarbons having a linear or a branched structure), alkenes (hydrocarbons with double bonds), cycloalkanes (saturated hydrocarbons containing a ring), and aromatic hydrocarbons (molecules containing benzene rings) [1, 2].
In order to study the heart disorder, Agladze's team created "arrhythmia in vitro", using azoTAB (azobenzene trimethylammonium bromide) whose molecule consists of two benzene rings connected by a bridge of two nitrogen atoms, said the study published in the journal PLOS ONE.
Instead of splitting layers of graphite with chemical or mechanical techniques, or putting energy into it, AGM's process involves catalytically cracking alcohol and then reassembling the carbon atoms into the benzene rings that form the basis of the graphene.
A complex class of organic compounds containing two or more fused benzene rings in a linear, angular or cluster arrangement, PAHs are generally considered carcinogenic and mutagenic in nature.
For example, 1H NMR spectrum of the complex trans[PdCl2(Phben)2] represented a broad singlet at around d 1.21ppm for methyl groups attached to the benzene rings. Chemical resonances at round 2.2 and 3.8 ppm appeared for the NH protons associated with palladium metal ion.
Phenanthrene is made up of three benzene rings, where 9,10-position has strong chemical reactivity, prone to oxidation.
Each unit of DMC consists of two benzene rings, one carbonyl carbon and [alpha]-[beta]- unsaturated carbons.
In addition, the deformation of the benzene ring, especially the deformation of the benzene rings at [C.sub.1], [C.sub.2], [C.sub.1]', and [C.sub.2]' atoms sites, also has a notable influence on the nonadiabatic transition of the excimer to ground state.
