RAMAN SPECTRA OF CRYSTALLINE HCN AND XCN COMPOUNDS
No full textAuthor Institution: D\'{e}partment de Chimie, Universit\'{e} LavalHydrogen cyanide and the cyanogen halides have characteristic chain-like structures in the solid state. Raman spectra of these compounds have been obtained and will be discussed in terms of their known crystal structures. Reasonable sets of force constants can be obtained for these solids by using a linear triatomic chain approximation

No full textLangmuir-Blodgett monolayers of a donor-acceptor diad TTF-σ-(trinitrofluorene) (8) with an extremely low HOMO-LUMO gap (0.3 eV) have been used to create molecular junction devices that show rectification behavior. By virtue of structural similarities and position of molecular orbitals, 8 is the closest well-studied analogue of the model Aviram-Ratner unimolecular rectifier (TTF-σ-TCNQ). Compressing the monolayer results in aligning the molecules, and is followed by a drastic increase in the rectification ratio. The direction of rectification depends on the electrodes used and is different in n-Si/8/Ti and Au/8/C16H33S-Hg junctions. The molecular nature of such behavior was corroborated by control experiments with fatty acids and by reversing the rectification direction with changing the molecular orientation (Au/D-σ-A versus Au/A-σ-D)
