Raman and Isotopic Studies of Large Presolar SiC Grains
Abstract
Raman spectra correlate with grain morphology: euhedral grains are cubic, grains with smooth, blocky morphology are hexagonal. An unusually large (30 µm) polycrystalline cubic X grain has wide Raman peaks, indicative of crystallographic disorder.
