Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Computer simulation of the optical spectrum of dimethylsulfoxide (CH3)2SO and dimethylsulfone (CH3)2SO2 or refractometric means of control E.E. MAIOROV, A.Ch. MASHEK, G.A. TSYGANKOVA, M.V. KHOKHLOVA, A.V. KURLOV, T.A. CHERNYAK, A.O. FADEEV In this article the two most important of the solvent dimethylsulfoxide and dimethylsulfone are listed, which for the rocket-space and aviation technology, as well as for optical instrument, in particular, industrial refractometry are promised. For quality control refractometric dimethylsulfoxide, dimethylsulfone and their aqueous solutions in the production cycle reliable quantitative data on the optical properties of these substances are obtained. The detailed analysis of the absorption spectrum of substances methods of quantum chemistry, which confirmed the results of the experiment is conducted. Results of the analysis of the electronic states of dimethylsulfoxide, dimethylsulfone are conducted: using a semi-empirical molecular orbital resifiyskoy model number 1 electronic levels of these substances were obtained. The absorption and transmission spectra in the ultraviolet and infrared wavelengths are analyzed. The data on the absorption at a wavelength λ = 271 nm, which substantially coincides with the experimental results, and the transmission spectra in the infrared wavelengths that correlate well with published data are obtained. Keywords: resifiyskaya model, ultraviolet spectrum, infrared spectrum, electronic level, dimethylsulfone, dimethylsulfoxide, industrial refractometry. Contacts: E-mail: majorov_ee@mail.ru Pp. 35-41.
