Acesso em: 08 set. 2015.1386-1425http://www.repositorio.ufop.br/handle/123456789/6101The mineral tilleyite-Y, a carbonate-silicate of calcium, has been studied by scanning electron microscopy with chemical analysis using energy dispersive spectroscopy (EDX) and Raman and infrared spectroscopy. Multiple carbonate stretching modes are observed and support the concept of non-equivalent carbonate units in the tilleyite structure. Multiple Raman and infrared bands in the OH stretching region are observed, proving the existence of water in different molecular environments in the structure of tilleyite. Vibrational spectroscopy offers new information on the mineral tilleyite.en-USTilleyiteSilicateCarbonateHydroxylInfrared and Raman spectroscopyArtigo publicado em periodicoO periódico Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy concede permissão para depósito deste artigo no Repositório Institucional da UFOP.
