Using terahertz time-domain spectroscopy to determine the glass transition temperature of heavy oils

Terahertz time-domain spectroscopy is used to measure the temperature-dependent refractive index of heavy oils down to 80 K. Evidence for a glass transition is observed, providing insight into the viscosity-temperature behavior of heavy oils.
