Based on NMR coupling experiments (Abraham, Chambers, & Thomas, 1993), for cis-1,3-cyclohexandiol, in protic solvents values of about 2.7 kcal/mol is obtained and in aprotic solvent CCl4, the value of 0.14 kcal

If released to air, cyclohexane will exist solely as a vapor in the ambient atmosphere, and will be degraded in the atmosphere by reaction with photochemically produced hydroxyl radicals, though direct photolysis is not expected due to the lack of absorption in the environmental spectrum. Volatiliza...
reference, and with the Pt1/CeO2catalyst. The near-edge fine structure (XANES) provides insights into the valence state of Pt (Fig.1c), while the extended X-ray adsorption fine structure part (EXAFS) provides information on the local bonding geometry33. The EXAFS data from the Pt1/CeO2c...
In the 13C{1H} NMR spectrum of PTA–Bztpy (Fig. S2†), the aromatic carbons were observed in the 118–156 ppm range while the methylene carbon of the benzyl group was observed at δ 64.72. The spectrum also reveals four signals confirming the N-alkylation of the PTA moiety, at δ ...
13, 14). While these results clearly indicate that no off-pathway aggregates are involved, we also attempted to study folding more directly by variable temperature 1H NMR spectroscopy. To this end, a 1.2 mM solution of M3 in C6D12/CDCl3 (84:16 v/v) was cooled from 333 to 283...

Dc-electrical conductivitywas studied for different PVK-additivecompositions, in isothermalconditions, using a sandwich Pt/sample/Pt cell. Byapplying the Poole-Frenkel theory a trapping state was evidenced showingtemperature and ...
