Halasinski, F. Salama, B. H. Foing, L. J. Allamandola, W. Schmidt, P. Ehrenfreund Title: Spectroscopy of large PAHs - Laboratory studies and comparison to the Diffuse Interstellar Bands Journal/Source: Astronomy & Astrophysics, 390, 1153-1170, (2002); DOI: 10.1051/0004-6361:20020478 Data: (diagram, table, disk): diagram, table Wavelength/Energy range: 200 - 510 nm Resolution: 0.4 - 11.9 nm (FWHM) Temperature: 4 K Temperature dependence: Pressure: Comments: The spectrum of neutral dicoronylene isolated in a neon matrix exhibits three structured band systems around 248.3, 333.3 and 444.6 nm. The spectrum of the ion is clearly dominated by two strong bands peaking at 682.5 nm and 1017.1 nm Author to whom correspondence should be addressed: (e-mail address):
