"Raman spectroscopy is ideal as it can be performed through transparent layers, such as evidence bags."Raman spectroscopy yields a characteristic "fingerprint" which can be compared to spectra of lipsticks of various types and brands, he said, allowing investigators do to determine identity of the lipstick involved quickly and non-destructively.</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
