# 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

## TL;DR

This study qualitatively analyzes the vibrational spectra of LiTaWO$_6$ to identify active modes, comparing with similar compounds and theoretical expectations, despite lacking crystalline samples.

## Contribution

It provides the first qualitative vibrational mode assignment for LiTaWO$_6$ using Raman and IR spectra without crystalline samples.

## Key findings

- Successfully assigned 8 of 10 expected vibrational modes
- Compared spectra with similar compounds to aid mode identification
- Demonstrated qualitative vibrational analysis without crystalline samples

## 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.
