Spectroscopic Quantification of Structurally-Bound Water in Spodumene

Alec R. Brenner

Abstract

I present polarized near-infrared absorption spectra of spodumene (LiAl(SiO3)2, the lithic clinopyroxene). I place emphasis on absorption features associated with O-H stretching (peaks near wavenumbers of ~3700-3300 cm-1), which I use as proxies for the presence of structurally-bound water (or OH-).
