Bocelli, Gabrielle; Grenier-Loustalot, Marie Florence; Iratcabal, Pierre (Cent.Chemical with cas number 89029-65-2 also plays role. Stud., Univ. Parma, Parma 43100, Italy). J. Mol. Struct., 102(1-2), 39-44 (English) 1983. CODEN: JMOSB4. ISSN: 0022-2860. DOCUMENT TYPE: Journal CA Section: 24 (Alicyclic Compounds) Section cross-reference(s): 75 An x-ray anal. of the title compd. (I) was carried out. The mol. assumes a trans conformation. The configuration of the sulfonate group is approx. tetrahedral; the cyclohexane ring is in the chair conformation. The presence of the :CH2 substituent on this ring causes some deformations in bond distances and angles of the ring. .

Quasifree electron mobility by the method of partial waves in liquid hydrocarbons and in fluid argon

Quasifree electron mobility by the method of partial waves in liquid hydrocarbons and in fluid argon. Vertes, Akos (Radiat. Lab., Univ. Notre Dame, Notre Dame, IN 46556, USA). J. Chem. Phys., 79(11), 5558-62 (English) 1983. CODEN: JCPSA6.Some commonly used reagents like 110-82-7 and 540-84-1 are used in this experiment. ISSN: 0021-9606. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Applicability of the fluctuation model was tested in the case of n-hexane, n-pentane, cyclohexane, 2,2-dimethylbutane, 2,2,4,4-tetramethylpentane, isooctane, and neopentane. The quasifree electrons were assumed to be scattered by the conduction state energy fluctuations of the liq. These fluctuations are, in turn, described as a consequence of d. fluctuations. The scattering potential is supposed to be square well like and the cross section is calcd. in terms of partial waves. Avs. due to the d. fluctuations and the electron kinetic energy distribution are detd. numerically. Except for the first three materials, the calcn. reproduced the exptl. mobilities with reasonable values of the square well radius, which is the only fitting parameter. Further extension of the description concerning the d. dependence of the low field mobility of fluid argon has been performed. The estd. fluctuation size as a function of d. increases monotonically at the min. of the mobility in accordance with the monotonic behavior of the isothermal compressibility in the same region. .
