Abstract:A recently developed concurrent analysis of fourpolarization IR (4P) data offers retrieval of three-dimensional (3D) orientation angles of macromolecules. Since it has only been for highly structured samples, it is important to explore its capabilities in samples lacking structure. Therefore, the nondestructive and label-free four polarization methodology was used to image the 3D orientation angles (4P-3D) and order parameters in different regions of anisotropic poly(L-lactic acid) thin film with coexisting am… Show more
