Marquina Física, Astronomía y Matemáticas diffraction Raman and infrared spectroscopy As it is well known, the physical characteristics of sulfur exhibit a wide range of interesting phenomena around 160±C [1]: a) A shear viscositychange of four orders of magnitude over a 25±C interval [2]. b) Changes in density and in sound velocity. c) Its color becomes darker andits refractive index and dielectric permittivity reach a minimum. d) Of special interest, because of its possible industrial applications, is thepolymerization process that occurs at around 160±C. Studies made in ultra pure sulfur (99.999%) have shed some light on this phenomenon,but a coherent picture is still missing. The properties of sulfur are strongly affected by impurities and dissolved gases, so that a great deal ofcare is necessary when performing these experiments. If the purpose is to take advantages of these properties for industrial applications, onemust rule out the use of ultra-pure sulfur and think in terms of a simple process with a commercial substance. In this work we shall reportsome infrared spectroscopy, Raman spectroscopy and X-ray diffraction results obtained in our attempts at the polymerization of commercialMexican sulfur. 2007 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57066108 https://www.redalyc.org/journal/570/57066108/ https://www.redalyc.org/journal/570/57066108/html/ https://www.redalyc.org/journal/570/57066108/57066108.epub https://www.redalyc.org/journal/570/57066108/movil en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
