Packing conflicts in the Z' = 5 structure of CF(3)(CF(2))(3)(CH(2))(10)COOH.
Dimers of the partially fluorinated amphiphile 1-(perfluorobutyl)undecanoic acid, CF(3)(CF(2))(3)(CH(2))(10)COOH, crystallize in the same basic packing arrangement found for many n-alkyl carboxylic acids. The unit cell of the fluorinated compound, however, contains five independent molecules rather than the one found for most n-alkyl carboxylic acids including CH(3)(CH(2))(13)COOH. The structur...
متن کاملcf 2 Semantics Revisited 1
Abstract argumentation frameworks nowadays provide the most popular formalization of argumentation on a conceptual level. Numerous semantics for this paradigm have been proposed, whereby cf2 semantics has shown to nicely solve particular problems concernend with odd-length cycles in such frameworks. In order to compare different semantics not only on a theoretical basis, it is necessary to prov...
متن کامل- 4 ’ ” EFFECT OF CF 3 H AND CF 3 Br ON LAMINAR DIFFUSION FLAMES IN NORMAL
Chemical inhibdion of dtiusion flames through addition of halogenatkd “inhibitors is a problem of significant practical and scientific interest. Extensive studies on diffusion flames in microgravity have shown that these flames have significantly different characteristics than those under normal gravity [1,2]. However, the mechanisms through which inhibitors reach the reaction zone to suppress ...
متن کاملA conformational and vibrational study of CF(3)COSCH(2)CH(3).
The molecular structure and conformational properties of S-ethyl trifluorothioacetate, CF(3)COSCH(2)CH(3), were determined in the gas phase by electron diffraction and vibrational spectroscopy (IR and Raman). The experimental investigations were supplemented by ab initio (Moller Plesset of second order) and density functional theory quantum chemical calculations at different levels of theory. B...
متن کاملAtmospheric chemistry of CF 3 CF @ CH 2 : Kinetics and mechanisms of gas - phase reactions with Cl atoms , OH radicals , and O 3
Long path length FTIR-smog chamber techniques were used to determine k(Cl + CF3CF@CH2) = (7.03 ± 0.59) · 10 , k(OH + CF3CF@CH2) = (1.05 ± 0.17) · 10 , and k(O3 + CF3CF@CH2) = (2.77 ± 0.21) · 10 21 cm molecule 1 s 1 in 700 Torr of N2, N2/O2, or air diluent at 296 K. CF3CF@CH2 has an atmospheric lifetime of approximately 11 days and a global warming potential (100 yr time horizon) of four. CF3CF@...
