TL;DR: In this article, the absolute total cross section (TCS) of the electron collision with molecules has been measured in a linear transmission experiment for impact energies from 0.5 to 250 eV.
Abstract: Absolute total cross section (TCS) of the electron collision with molecules has been measured in a linear transmission experiment for impact energies from 0.5 to 250 eV. The TCS function is dominated by a steep rise towards low energies below 3 eV. At energies above the minimum at 3 eV the TCS shows another enhancement spanned up to about 70 eV on which some resonant-like features are visible: the maximum centred near 6.5 eV and two weak peaks at 16 and 25 eV, respectively. A comparison with the recent measurements taken in the same laboratory for and and for other targets of the same symmetry is made to search for similarities and/or differences between electron scattering TCSs for tetrahedral molecules. The data demonstrate that the general shape of the low-energy TCS for tetrahedral molecules depends on external rather than on central atoms.

TL;DR: In this paper, seven new Cu(II and Co(II) coordination compounds are synthesized with the general formula M(L)(X)2(Y)z, in which L stands for the known ligand bis(2-benzimidazolyl)propane and for the novel ligands bis( 2-benzinimidaxolyl)-2-butane and bis-(2-bitzimidel)-3butane, M =Cu(II), and X =Cl and Br, Y =water and/or ethanol

TL;DR: The structure of tricyclohexyltin chloride has been determined by X-ray analysis as mentioned in this paper, which is consistent with the tetrahedral geometry when distortions are taken into account in the treatment of the point charge model.

TL;DR: A range of aluminate sodalites of general formula M8(AlO2)12, where M and X are a divalent cation and anion, respectively, has been synthesised and relations between the Al-O-Al bond angles and the 27Al chemical shift are determined.
