In this article we present our results on THz-spectroscopy of intra-excitonic transitions. Especially, properties of different III-V multi quantum well systems are investigated. After an introduction to the methodology of THz Time-Domain Spectroscopy, results for both a GaAs/(AlGa)As and a (GaIn)As/GaAs multi quantum well structure are presented. We find good agreement with previous experiments [1,2] for the GaAs/(AlGa)As structure, while the (GaIn)As/GaAs structure behaves significantly different.
