Abstract

The a-, σ- and π-spectra of quartz in the IR regions were measured under FTIR spectroscopy, and overtone and combination modes perpendicular to the c-axis of quartz were confirmed to be electric vector active by the coincidence of the a-spectrum with the σ-spectrum among the three kinds of spectra. Absorption coefficients of overtone and combination modes intrinsic to the a- σ-, and п-spectra of quartz were measured. The thickness of quartz thin sections can be determined by applying the absorption coefficients obtained from the α- and σ-spectra to the polarized IR absorption spectra measured under E ⊥ the c-axis.
