[The use of combined spectroscopy in analytical toxicology (author's transl)].

The combined application of the four spectrometric techniques UV, IR, NMR and MS is an important analytical tool for the identification of the increasing number of potential poisons with which the analysts in the fields of forensic sciences and toxicology are confronted. Some of the contributions of these techniques to toxicological analyses are reviewed and illustrated by a few examples. Furthermore, the incorporation of the four methods into the analytical scheme, the requirements with respect to quantity and purity of the unkown substances, as well as the different possibilities for the combination of separation and identification techniques are outlined.
