Cooperative intramolecular hydrogen bond and conformations of thiocalix[4]arene molecules

Kovalenko V.; Chernova A.; Borisoglebskaya E.; Katsyuba S.; Zverev V.; Shagidullin R.; Antipin I.; Solov'eva S.; Stoikov I.; Konovalov A. (2002)

The joint FTIR spectroscopic study and ab initio quantum-chemical calculations (HF/3-21G and PBE/TZ2P methods) showed that thiocalix[4] arene molecules adopt the cone conformation in CCl4 solutions. The weakening of the ...
Dipole moments and molecular spectra of certain derivatives of dibenzalacetone

Arbuzov B.; Yuldasheva L.; Anonimova I.; Shagidullin R.; Chernova A.; Fazliev D. (1969)

From the spectral data it may be assumed that di-p-chlorodibenzalacetone exists in solution as a mixture of s-cis,s-cis- and s-cis, s-trans-conformations, possessing a trans-configuration of both ethylenic bonds, which ...
Fourier transform IR spectra and structure of 2-substituted 1-nitro- and 1-bromo-1-nitroethenes

Gazizova A.; Shagidullin R.; Chernova A.; Vereshchagina Y.; Chachkov D.; Ishmaeva E.; Berestovitskaya V. (2007)

Molecular structure and vibrational spectra of 2- trichloromethyl(ethoxycarbonyl)-1-nitroethenes and 2- trichloromethyl(ethoxycarbonyl)-1-bromo-1-nitroethenes were calculated in terms of the density functional theory ...
Intra- and intermolecular interactions in the series of acyclic and macrocyclic compounds containing nucleotide bases and their derivatives

Semenov V.; Chernova A.; Shagidullin R.; Shcherbakov V.; Reznik V.; Chevela V. (2007)

Intra-and intermolecular interactions in acyclic compounds containing nucleotide base (uracil and thymine) derivatives and their macrocyclic analogs (pyrimidinophanes) were studied by IR, UV, luminescence, and NMR spectroscopy. ...
IR and NMR spectra, intramolecular hydrogen bonding and conformations of mercaptothiacalix[4]arene molecules and their para-tert-butyl-derivative

Katsyuba S.; Zvereva E.; Chernova A.; Shagidullin A.; Solovieva S.; Antipin I.; Konovalov A. (2008)

It is demonstrated that the introduction of p-tert-butyl groups dramatically influences the conformational behaviour of the mercaptothiacalix[4] arene molecules. Quantum-chemical computations in combination with IR and NMR ...
IR and NMR spectra, intramolecular hydrogen bonding and conformations of para-tert-butyl-aminothiacalix[4]arene in solid state and chloroform solution

Zvereva E.; Katsyuba S.; Vandyukov A.; Chernova A.; Kovalenko V.; Solovieva S.; Antipin I.; Konovalov A. (2010)

It is demonstrated that dissolution of aminothiacalix[4]arene in chloroform results in transformation of 1,3-alternate conformation, adopted in single-crystal and bulk polycrystalline solids, to the pinched-cone form. This ...
Isomerism of certain derivatives of benzalacetophenone

Arbuzov B.; Yuldasheva L.; Anonimova I.; Shagidullin R.; Chernova A.; Fazliev D. (1969)

1. p-Nitro-, m-nitro-, and p-chlorobenzalacetophenone (mp 113-114°C) have a trans-configuration of the ethylenic bonds and represent the s-cis-conformer both in solid form and in solution, with a possible admixture of the ...
New method of "reading" strongly-correlated sequences: Treatment and analysis of the CCD-matrix noise

Nigmatullin R.; Chernova A.; Pershin S.; Lykianchenko V. (2011)

Description of random sequences in strongly-correlated systems with the help of β - distribution has been considered. This new method was applied to analysis of CCD-matrix noises recorded at different temperatures. Every ...
Novel Co(II) phthalocyanines of extended periphery and their water-soluble derivatives. Synthesis, spectral properties and catalytic activity

Filippova A.; Vashurin A.; Znoyko S.; Kuzmin I.; Razumov M.; Chernova A.; Shaposhnikov G.; Koifman O. (2017)

© 2017 Elsevier B.V. Novel complexes of cobalt and copper with substituted phthalocyanines were synthesized and characterized. Their water-soluble derivatives were obtained by sulfonation under mild conditions and structurally ...
Specifics of self-organization and properties of highly dilute aqueous solutions of polyoxidonium

Ryzhkina I.; Sergeeva S.; Safiullin R.; Ryzhkin S.; Margulis A.; Murtazina L.; Timosheva A.; Chernova A.; Kadirov M.; Konovalov A. (2016)

© 2016, Springer Science+Business Media New York.Using a combination of physicochemical methods (dynamic and electrophoretic light scattering (DLS and ELS, respectively), nanoparticle tracking analysis, atomic force and ...
Vibrational spectra, co-operative intramolecular hydrogen bonding and conformations of calix[4]arene and thiacalix[4]arene molecules and their para-tert-butyl derivatives

Katsyuba S.; Kovalenko V.; Chernova A.; Vandyukova E.; Zverev V.; Shagidullin R.; Antipin I.; Solovieva S.; Stoikov I.; Konovalov A. (2005)

The IR and Raman spectra and conformations of calix[4]arene, thiacalix[4]arene and their p-rerf-butyl derivatives have been analysed within the framework of scaled quantum mechanics (SQM). It is shown that the introduction ...
