• 論文の詳細を見る

• Raman spectra of micro-diamonds contained in Antarctic ureilite, Y-791538 were observed by laser Raman microprobe. Based on the resultant spectra, diamond particulates could be divided mainly to two groups. For the first group, observed spectra have ordinary Raman shift at 1332cm-1 with fluorescence band. On the other hand, spectra classified into the second group have anomalous Raman shift at 1323cm-1, free from the fluorescence band. Three possible interpretations are proposed for the significant difference in the Raman shift.
