Acid dissolution experiments - Carbonates and the 6.8-micrometer bands in interplanetary dust particles
Author and Affiliation:
Sandford, S. A.(NASA Ames Research Center, Moffett Field, CA)
Abstract: A chemical dissolution experiment on an interplanetary dust particle (IDP) showed that carbonates, not acid-insoluble organic compounds, were responsible for virtually all the absorption at 6.8 micrometers seen in the infrared spectra of this particle. The IDP examined had an infrared spectrum characteristic of layer-lattice silicates and belongs to a class of IDP's whose spectra resemble those of protostellar objects like W33 A, which also exhibit a band at 6.8 micrometers.
