Terahertz spectra databases require crystallographic information

TL;DR

This paper emphasizes the importance of including crystallographic information in terahertz spectral databases to improve the accuracy of material identification and reduce misinterpretations caused by polymorphic variations.

Contribution

It advocates for integrating structural data into THz spectral databases to enhance their reliability and interpretability.

Findings

Crystallographic info improves spectral analysis accuracy

Current databases lack structural data, leading to misinterpretations

Including structural data can differentiate polymorphic forms more effectively

Abstract

Although the sensitivity of THz spectra to the crystal form of the sample being analysed makes it an ideal tool for differentiating polymorphic forms of crystalline materials, the lack of adequate knowledge about the THz response to various materials often results in misinterpretations. The inclusion of structural information in THz spectral databases of crystalline substances is therefore suggested.
