SPECTROSCOPIC_DISCUSSION:

The spectrum has a sharp absorption edge centered at about 0.35 microns with shoulders at 0.27 and 0.35 microns. A spectral downturn begins at 1.4 microns and continues toward longer wavelengths. There is a broad symmetrical absorption centered at 2.0273 microns and a narrow absorptions at 2.3434 microns. There is a moderately intense absorption at 4.05 microns and an more intense absorption at 4.66 microns in the MIR.
