A study of absorption bands in simulated lunar glasses resulted in the discovery of a Ti4+-O2– charge transfer band at 0.26 micrometer and two Fe2+-Ti4+ bands at 0.34 and 0.42 micrometer. These results indicate that the properties of lunar soil are somewhat affected by the glass content but are controlled by other factors.
