Lunar soil: iron and titanium bands in the glass fraction.
A study of absorption bands in simulated lunar glasses resulted in the discovery of a Ti(4+)-O(2-) charge transfer band at 0.26 micrometer and two Fe(2+)-Ti(4+) 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.
