aromaticity

(əˌrəʊməˈtɪsɪtɪ)
n
1. (Chemistry) the property of certain planar cyclic conjugated molecules, esp benzene, of behaving like unsaturated molecules and undergoing substitution reactions rather than addition as a result of delocalization of electrons in the ring
2. the quality or state of having an aroma

The new metal structures show a tantalizing trait called aromaticity. This molecule-stabilizing property was named after the first such molecules identified, including benzene, which have noticeable aromas.
These polymers lacked the highly ordered, stiff backbones of conventional polyimides, and this loss of aromaticity greatly diminished the ability to compete with high performance aromatic polyimides.
Despite that, all HI and PI values were less than one across the sampled treatment combinations (Table 1), implying lower aromaticity of [C.sub.HA].
This difference in pyrolysis among the three [beta] resins was caused by the dissimilarity in their aromaticity index (Iar) and CH3/CH2 ratio; these factors significantly affect the aromaticity and number of aliphatic side chains in [beta] resin.
The higher H/C ratio of the CS-Fe over CS indicated that more original organic matter was preserved in the iron-loaded biochar and showed lower overall aromaticity. The higher O/C ratios of the CS-Fe indicated higher polarity when compared to CS [22].
It has been demonstrated that the most important compositions of DOM include three categories: humic substances, polysaccharides, and proteins [18], while these substances should play an essential role on the adsorption of antibiotics by their hydrophobicity, aromaticity, and functionality properties.
In this work, 55 types of 1D and 2D descriptors were used after removing salt and detecting aromaticity information from a molecule.
However, the aromaticity of G1 makes it much more stable than G2, which displays an exocyclic double bond between C(4) and C (15).
Their topics are mathematical chemistry, graph theory and chemistry, characteristic polynomial, structure-activity, molecular descriptors, partial ordering, novel molecular matrices, on highly similar molecules, aromaticity revisited, clar aromatic sextet, renormalization in chemistry, graphical bioinformatics, and beauties and sleeping beauties in science.
This happens in a way that increases in the aromaticity of D-amino bridges and replacing of hydroxyl groups with methoxy (except some items) will lead to increase in anticancer feature [2, 28].
The salicylaldimines exist predominantly in-OH tautomeric form in crystalline state and the reason behind this is the loss of ring aromaticity [26].
