On the Presence of Phyllosilicate Minerals in the Interstellar Grainsees, in the presence of H.O, would result in hydrous or phyllosilicates, the silicate type most abundant in the type I carbonaceous chondrites. Infrared spectra of small particles (∼ 0.1 μ) of the high temperature condensates, olivine and pyroxene, at 300 K and 4 K do not give a good match to the in

The Influence of Grain Mantles on the Formation of Hydrogen Molecules on Grain Surfacesnsities has been measured. Values of ./. are for condensed CO 340 K, CO. 800 K, H.O 850 K and for ‘dirty’ graphite 980 K and ‘dirty’ copper 800 K. From these measurements temperature ranges in which H atoms might combine on the surface to form H. molecules are estimated..Duley has discussed the form
