Resonance Raman investigation and semiempirical calculations of the bis(dicyanomethylene)croconate ion

Autor: Paulo R. S. Santos, L.F. Cappa de Oliveira, J.G. da Silva Lopes, P.M.V.B. Barone, Mauro C. C. Ribeiro

Publikováno v: Journal of Molecular Structure. 510:97-105

The assignments of the optical and vibrational spectra of bis(dicyano)croconate are proposed on the basis of the resonance Raman excitation profiles as well as semi-empirical calculations at the AM1 and PM3 levels. The absorption band at 532 nm is as

Hydrodynamic, optical and spectroscopic studies of some organic-aqueous binary systems

Autor: Paulo R. S. Santos, H H A Menezes, JoséA.G. Arêas, Elizabeth Pinheiro Gomes Arêas

Publikováno v: Journal of Molecular Liquids. 79:45-58

The peculiar occurrence of pseudoplastic behaviour of protein solutions in certain organic-aqueous media has been subject of previous studies [Areas et al., J. Coll. Interface Sci., 180 (1996), 578]. The role of the solvent in these events has been s

Vibrational dephasing in liquid carbonyl sulfide: comparison between molecular dynamics of rigid and flexible molecular models

Autor: Mauro C. C. Ribeiro, Paulo R. S. Santos

Publikováno v: Journal of Molecular Liquids. 71:25-38

Vibrational dephasing of the ν 1 and ν 3 stretching modes of carbonyl sulfide, OCS, was investigated by computer simulations of the liquid in the states corresponding to 183, 243 and 273 K. Perturbation theory plus simulation of rigid molecules res

Computer simulation of vibrational dephasing in carbon disulfide

Autor: Paulo R. S. Santos, Mauro C. C. Ribeiro

Publikováno v: Journal of Molecular Liquids. 68:33-54

Vibrational dephasing of the totally symmetric stretching mode of liquid carbon disulfide at different pressures at room temperature is investigated by molecular dynamics simulation. The thermodynamic states simulated correspond to the liquid at atmo
