Vol. 428 (2014) p. 67-74 | Título da revista, periódico, livro ou evento: | Chemical Physics | Volume: | 428 | Resumo: | A new semi-organic compound, 6-aminoquinolinium iodide monohydrate (I), has been synthesized and characterized by single crystal X-ray diffraction, UV–vis absorption and fluorescence spectroscopy and nonlinear optical (NLO) measurements. The second- and third-order NLO responses were investigated with the second- and third-harmonic Maker fringes techniques, carried out on thin films at a fundamental wavelength of 1064 nm. From the molecular structure, the molecular hyperpolarizability tensors were determined with density functional theory and second-order Møller–Plesset perturbation method. The second- and third-order susceptibility tensors of the reported crystal were evaluated using the oriented gas model with the Lorenz–Lorentz and the Wortmann–Bishop local-field corrections. The calculations using the Wortmann–Bishop local-field were able to reproduce the correct order of magnitude of the experimental third-order susceptibilities. The value of χ(3) obtained by summing the effective third-order polarizability calculated for the asymmetric unit surrounded by ESP-derived charges have also the same order of magnitude of the experimental. | URI: | https://hdl.handle.net/10316/27120 | ISSN: | 0301-0104 | DOI: | 10.1016/j.chemphys.2013.11.001 | Direitos: | openAccess |
