IR-TMOA is a recently developed experimental technique that enables one to determine the full three dimensional molecular order parameter tensor with respect to a sample coordinate system (reflecting degree of order and mean orientation directions). Relying on the dependence of the IR spectra on polarization and an intentional inclination of the sample with respect to the optical axis, specific information for the various molecular moieties in any IR translucent material can be obtained. The approach is of fundamental interest in polymer science and industry1, for liquid crystal applications2,3, organic electrets and it can provide insight into interactions in confined geometries2,4. We will present examples from each of these fields emphasizing the multiple opportunities of this technique.
