Title
Optical constants of amorphous and crystalline H 2O-ice in the near infrared from 1.1 to 2.6 \ensuremathμm
Abstract
Using new laboratory spectra, we have calculated the real and imaginary parts of the index of refraction of amorphous and crystalline H2O-ice from 20 to 150 K in the frequency range 9000-3800 cm−1 (1.1-2.6 μm) at a spectral resolution of 1 cm−1. These optical constants can be used to create model spectra for comparison to spectra from Solar System objects. We also analyzed the differences between the amorphous and crystalline H2O-ice spectra, including weakening of bands and shifting of bands to shorter wavelength in amorphous H2O-ice spectra. We have also observed two spectrally distinct phases of amorphous H2O-ice.
