title: Saturn's Rings: Identification of Water Frost.
abstract: A recently published infrared spectrum of Saturn's rings resembles our laboratory spectra of water frosts. Furthermore, there are discrepancies between the ring spectrum and ammonia frost spectra in the 2- to 2.5-micro region. These discrepancies render unlikely a reported ideti tification of ammonia frost in the ring spectrum.
