Identification of a mid-infrared electronic absorption band of Fe^(2+) in the distorted M(2) site of Orthopyroxene, (Mg, Fe)SiO_3

Abstract

An electronic absorption band of Fe^(2+) in the distorted, six-coordinate M(2) site of the common mineral orthopyroxene, (Mg, Fe)SiO_3, is identified at 2350 cm^(−1). This band is attributed to the A_1 → B_2 transition within the split ^5T_(2g) state of Fe^(2+) in C_(2V) symmetry.
