Much interest in this area is focused on peripheral pi-systems and aromaticity
, and on carcinogenicity.

and Other Special Properties of Heterocycles: Pi-Deficient Ring Systems
The WEOC concentration of the filtrate was determined with a Multi N/C 3100 analyzer (Jena, Germany), while the UV absorbance characteristic at 280 nm was measured by UV/VIS-2450 to evaluate the aromaticity
of biochar WEOC content (Weishaar et al.
Due to aromaticity
in the backbone of the amide segment and bulky pendant group the growth per layer pair was less.
Substitution and elimination reactions are followed by a chapter on spectroscopy, then moving on to reactions at pi bonds, radicals, conjugation, and aromaticity
It is interesting to note that l-naphthyloxy and biphenyloxy containing polymers were more stable compared to phenyloxy containing polymers, attributed to increase in aromaticity
, size, and number of aromatic rings.
Molar H/C ratios of the different biochars indicated that the PS biochar is likely to remain the most stable in soil, while the GW350 had the lowest level of aromaticity
and its turnover time in soil is likely to be the shortest.
heavy analogues of aromatic compounds; including a comparison between organometallic and organic aromaticity

The of aliphatic C : aromatic C and hydrophobic C : hydrophilic C ratios and aromaticity
percentage in soil under Chinese hickory were not affected by intercropping.
45 suggested high levels of aromaticity
and thus stability in soil (Krull et al.
Each SARAs fraction is a compound mixture with a complexity, aromaticity
, heteroatom content, and molecular weight that increase in the order S < A < R < As [6, 7].
