science-softCon uv/vis spectra data base; www.uv-spectra.de, (C) science-softCon 2009 Substance: decacyclene Other Names: Formula: C36H18 CAS-No.: Study: spectroscopy Authors: R. Ruiterkamp, T. 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 - 500 nm Resolution: 0.3 - 25.3 nm (FWHM) Temperature: 4 K Temperature dependence: Pressure: Comments: The spectrum is composed of two broad absorption band systems centered around 251.8 and 364.2 nm, respectively with superimposed fine structure. New broad bands apear at 539.7, 813.0 and 1095.8 after VUV irradiation of decacyclene in a Ne/NO2 matrix. Author to whom correspondence should be addressed: (e-mail address):
