FTIR-Goniometry — •Patrick Koelsch, Michael Tammer, and Friedrich Kremer — University of Leipzig, Faculty of Physics and Earth Science, Linnestrasse 5, 04103 Leipzig

Fourier Transform Infrared (FTIR)-Goniometry is a novel spectroscopic tool in which the principle of goniometry (as known from x-ray scattering) is combined with (polarized) IR spectroscopy. In practice a thin (µm thick) sample is intentionally inclined in adjustable spatial directions with respect to the optical axis of the spectrometer. An algorithm will be presented to deduce the mean orientation and the distribution of the different molecular moieties in the sample from the measured transmission. Thereby advantage is taken from the specificity of the IR spectral region as a “fingerprint” regime.

This offers a manifold of novel perspectives for molecular physics and materials science. Examples will be discussed.
