Identification of Potential Estrogenic Environmental Pollutants by Terahertz Transmission Spectroscopy

Abstract

Using magnetically enhanced terahertz radiation from InAs, various naphthols, which exhibits estrogenic like activity and are potentially mimic natural hormones, are studied. The experimental results show that the naphthols, depicted by the position of the hydroxyl (-OH) component at different carbon atom sites of the naphthalene compound, are distinguishable based on the absorption of THz radiation. It is found that the THz radiation absorption is strongly related to the crystal symmetry and dipole moment of these isomers.
