Outline of Final Research Achievements

Terahertz radiation, located in the electromagnetic spectrum between radio waves and visible light, is nonionizing in soft matter and its propagation is amenable to optical handling. We applied Fourier transform terahertz spectroscopy to an investigation of polypropylenes (PPs) with different crystallinities and tacticities. We also investigated polyethylene terephthalates (PETs) with different history of mechanical and thermal denaturation. Broadband THz spectroscopy offers a nondestructive, noninvasive inspection technique for general-purpose plastics.
