SPECTROSCOPIC_DISCUSSION:

A spectrum was collected of the top surface of this sample. The spectrum is flat at about 43% reflectance at 1.0 microns with a strong reflectance peak at 0.5 microns giving the sample its green color. There are also moderately strong absorptions at 1.1429, 1.2083, and 1.4277 microns and strong absorptions at 1.6787, 2.1435, 2.1660, 2.1881, 2.2952, 2.2604, and 2.3524 microns. The absorptions at 1.6787 and in the 2.3 micron region are C-H related.
