Some interplanetary dust particles (IDPs), collected by NASA from the Earth's stratosphere, are the most primitive extraterrestrial material available for laboratory analysis. Many exhibit isotopic anomalies in H, N, and 0, suggesting they contain preserved interstellar matter. We report the preliminary results of a comparison of the infrared absorption spectra of sub-units of the IDPs with astronomical spectra of interstellar grains.
