The H$_x$Li$_{1-x}$TaWO$_6.n$H$_2$O trirutile structure characterization through Raman and IR spectra comparison: The non-center symmetric case

Abstract

We have performed the LiTaWO$_6$ vibrational studies for both Raman and infrared actives modes. Although we do not have crystalline samples, the study was conducted qualitatively, firstly comparing the sample with similar compounds in the literature, and secondly comparing both Raman and infrared spectra of the LiTaWO$_6$ compound. Although the procedure is limited, we can assign 8 of the 10 Raman-IR active modes expected by Group Theory.
