Absorption measurements on diphenyl compounds in the microwave region was written by Hufnagel, F.;Klages, G.;Knobloch, P.. And the article was included in Zeitschrift fuer Naturforschung in 1962.Category: pyridine-derivatives This article mentions the following:
Recent measurements of the dielec. absorption at 0.7, 1.5, 10.1, and 60 cm. wavelengths are discussed in terms of the long wave relaxation time tL and flattening of the absorption curve (v %) in relation to the Debye curve. The dipole moments, tL, and v are tabulated for Ph2CO, Ph2O, Ph2S, 4,4′-dibromodiphenyl sulfide, 2-pyridyl Ph ether, m-nitrophenyl Ph ether, 4-pyridyl Ph ether, Ph2CH2, dinaphthyl ether, biphenylyl Ph ether, hydroquinone diphenyl ether, resorcinol diphenyl ether, and phenoxathiin. In the experiment, the researchers used many compounds, for example, 2-Phenoxypyridine (cas: 4783-68-0Category: pyridine-derivatives).
2-Phenoxypyridine (cas: 4783-68-0) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Category: pyridine-derivatives
