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 pin) 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. (C) 2008 Elsevier Inc. All rights reserved.
