Identification of Natural Tourmaline and Similar Gems by Diffuse Reflection Fourier Transform Middle Infrared Spectrum

Abstract:

Article Preview

By using the infrared reflection spectrum analysis technique, natural tourmaline and imitation tourmaline, similar tourmalines were investigated. The results show that the main absorption peaks of natural tourmaline are seven peaks at 1314cm-1, 1118cm-1, 1039cm-1, 999cm-1, 601cm-1, 513cm-1, 454 cm-1. The main absorption peaks of composite tourmaline and imitation tourmaline are different from natural tourmaline. The results are useful for identifying them.
