SPECTROSCOPIC_DISCUSSION:
Spectrum was collected of the top surface of this sample. The spectrum slopes down toward longer wavelengths from a high of 84% reflectance at 0.55 microns. There are also moderately strong absorptions at 1.1429, 1.2082, and 1.4278 microns and strong absorptions at 1.6781, 1.9054, 1.9482, 2.1429, 2.1671, 2.2662, 2.2978, 2.3524, and 2.3524 microns. The absorptions at 1.6781 and in the 2.3 micron region are C-H related.
