Dataset associated with “Understanding the Physics of the Auxetic Response in a Liquid Crystal Elastomer”.

Contains polarised Raman spectroscopy of a liquid crystal elastomer known to display an auxetic response and a mechanical Fréedericksz transition as a function of strain. Files include full evolution of the uniaxial and biaxial order parameters as a function of strain parallel and perpindicular to the director. Depolarization data is provided for various bond vibrations to determine the director behaviour as a function of strain.
