Breathers in hydrogen-bonded chains
نویسنده
چکیده
In the framework of the one-component model for hydrogen-bonded chains developed by Zolotaryuk and Pnevmatikos [Phys. Lett. A 143 (1990) 233], we study analytically and numerically breather excitations in the continuum and the discrete-carrier limits. We demonstrate that the breathers show high-stability properties especially in the case when the on-site potential is symmetric. We also consider absorption of the energy of an external ac field by breathers and discuss possible applications of this effect to the nonlinear dynamics of hydrogen-bonded systems.

3-Fluorosalicylaldoxime at 6.5 GPa
3-Fluoro-salicylaldoxime, C(7)H(6)FNO(2), unlike many salicylaldoxime derivatives, forms a crystal structure containing hydrogen-bonded chains rather than centrosymmetric hydrogen-bonded ring motifs. Each chain inter-acts with two chains above and two chains below via π-π stacking contacts [shortest centroid-centroid distance = 3.295 (1) Å]. This structure at 6.5 GPa represents the final point ...
متن کاملPolymorphs of anhydrous theophylline: stable form IV consists of dimer pairs and metastable form I consists of hydrogen-bonded chains.
The structure of a previously unreported polymorph of anhydrous theophylline (1,3-dimethyl-3,7-dihydro-1H-purine-2,6-dione), C(7)H(8)N(4)O(2), has been determined at 100 K and shown to have monoclinic symmetry with Z' = 2. The structure is named form IV and experimental observation indicates that this is the stable form of the material. The molecular packing consists of discrete hydrogen-bonded...
متن کاملA molecular dynamics study of water chain formation in the proton-conducting K channel of cytochrome c oxidase.
The formation of water chains in cytochrome c oxidase (CcO) is studied by molecular dynamics (MD). Focus is on water chains in the K channel that can supply a proton to the binuclear center (the heme a3 Fe/CuB region), the site of O2 reduction. By assessing the presence of chains of any length on a short time scale (0.1 ps), a view of the kinds of chains and their persistence is obtained. Chain...

The molecules of 3-tert-butyl-5-[(4-methoxybenzyl)amino]-1-phenyl-1H-pyrazole, C21H25N3O, are linked into simple C9 chains by a single C-H...N hydrogen bond. 5-[(Benzotriazol-1-ylmethyl)(4-methoxybenzyl)amino]-3-tert-butyl-1-phenyl-1H-pyrazole, C28H30N6O, crystallizes with Z' = 2 in the space group P2(1)/c. The molecules are weakly linked into centrosymmetric tetramolecular aggregates by a comb...
متن کاملAsymptotic dynamics of breathers in Fermi-Pasta-Ulam chains.
We carry out a numerical study of the asymptotic dynamics of breathers in finite Fermi-Pasta-Ulam chains at zero and nonzero temperatures. While at zero temperature such breathers remain essentially stationary and decay extremely slowly over wide parameter ranges, thermal fluctuations tend to lead to breather motion and more rapid decay. In both cases the decay is essentially exponential over l...
