Directional hemispheric (diffuse) reflectance spectra of lunar samples measured by John B. Adams (currently at Department of Geological sciences, Washington University, Seattle, WA 98195). These data were acquired using a Beckman Dk-2A, using both gold and smoked MgO as standards, during the 1970's.
Examples of these spectra are reported in a series of science articles:
