Description
Biconical FTIR reflectance spectrum of red and blue faces of a 0.5-mm particle in the OREX-803124-0 aggregate sample of asteroid Bennu were measured using Thermo Nexus 870 FTIR spectrometer with PIKE biconical diffuse reflectance accessory having a gold-coated mirror. The incidence and emergence rays are conically shaped, and the incidence beam aperture size was 10. The incidence and emergence rays are off the plane perpendicular to the sample surface, and they are cone-shaped centering around 30 and -30 degrees from the vertical axis. This was a remeasurement of the same sample measured two months earlier to see any effect of water adsorption.
