DFT Study of Hydrogen Bonding on Calix[8]arene as Nanostructure Compound
An azobenzene bridge was introduced into the lower (or smaller) rim of p-tert-butylcalix[8]arene to form 1,5-singly bridged calix[8]arene derivatives, respectively. Bridged calix[8]arene of conformationally rigid wereisolated. The stability of the two structures of bridged calix[8]arenes have been compared.The study of organicstructure to form nanoporous structures is a well known in chemistry ...
متن کاملNew Book Proposal Excited-State Hydrogen Bonding and Hydrogen Tranfser
This chapter reviews recent results on the vibrational dynamics of hydrogen-bonded nucleic acid base pairs putting special emphasis on the signatures of hydrogen bonding in linear and nonlinear infrared spectroscopy. Hybrid QM/MM trajectory simulations are discussed as a means for obtaining information on geometric correlations and hydrogen bond fluctuations in the condensed phase. A detailed a...

متن کاملHydrogen bonding with a hydrogen bond: The methane–water complex and the penta-coordinate carbon
Ab initio and atoms in molecules (AIM) theoretical studies have been used to show that in a 1:1 complex formed between CH4 and H2O, CH4 acting as a hydrogen bond acceptor leads to the global minimum structure. There is a bond path connecting C to the H of H2O revealing a penta-coordinate carbon that could be the precursor to the CH5 . It appears to be a general feature in CH4 HX complexes (X = ...

molecules to evolve in the test tube. With the discovery of catalytic RNA, and advances in nucleic acid amplification techniques such as the polymerase chain reaction, it became possible to construct laboratory systems that allow the Darwinian evolution of functional RNA (and later DNA) molecules. This is not evolution based on natural selection, but rather directed evolution based on selection...
