Gas-phase electronic spectra of several carbon chain anions have been measured in the laboratory and compared with diffuse interstellar bands (DIBs). The lowest energy transition C−7 shows seven prominent narrow bands, five which show striking matches DIBs while other peaks are obscured by broader, more intense, DIBs. origin corresponding C−6, C−8, C−9 also appear to match These observations provide first compelling evidence for identification some DIB carriers. presented data on these...

Colour variations within the same type of gemstone are caused by different abundances trace elements. But apart from producing pretty colours, analysis elements in gemstones is frequently used to distinguish between synthetic and natural specimen, for provenance determination, treatment detection [1]. Every element composition closely tied its geological origin; thus, it possible determine according those unique ‘fingerprints’. However, some gemstones, such as sapphires,...
