L. Kokkin, T. P. Troy, M. Nakajima, K. Nauta, T. D. Varberg, G. F. Metha, N. T. Lucas, T. W. Schmidt Title: The Optical Spectrum of a Large Isolated Polycyclic Aromatic Hydrocarbon: Hexa-peri-hexabenzocoronene, C42H18 Journal/Source: Astrophys. J., 681, L49-L51, (2008); doi: 10.1086/590207 Data: (diagram, table, disk): Energy/Wavelength range: 408.0 - 453.0 nm Resolution: Temperature: Temperature dependence: Pressure/Concentration: Comments: Vibronic bands of the first electronic transition were observed in the 4080-4530 Å range. The strongest feature at 4264 Å is estimated to have an oscillator strength of f = 1.4 × 10-3. Author to whom correspondence should be addressed: (e-mail address):
