Abstract

Abstract

To explore the characteristics of terahertz absorption spectra of lipid macromolecules, terahertz time-domain spectroscopy (THz-TDS) is applied to seven types of plant oils and two types of blend oils. The oils are measured in the frequency range extending from 0 to 80 wavenumbers. The absorption features of the oils are different in such a frequency range, indicating that THz-TDS can be used to distinguish different types of oils, which is the basis for analyzing oil composition and distinguishing oil mixtures with THz spectroscopy.
