Terahertz spectroscopy of crystalline and non-crystalline solids is probably one of the most active research fields within the terahertz community. Many potential applications, amongst which spectral recognition is probably one of the most prominent, have significantly stimulated the development of commercial systems and have spurred an increased technical advancement. However, the topic is very complex and multifaceted. Therefore, it is beyond the scope of this chapter to provide a fully comprehensive review of the works performed in this area. We would rather like to demonstrate, based on some selected examples, the potential the technique holds for various different applications. A particular focus will be given to data analysis and, in particular, how we may account for effects resulting from non-ideal sample preparation.
