The 5.25 & 5.7 m Astronomical Polycyclic Aromatic Hydrocarbon Emission Features
C. Boersma, A. L. Mattioda, C. W. Bauschlicher +3
Astronomical mid-IR spectra show two minor PAH features at 5.25 and 5.7 m (1905 and 1754 cm) that hitherto have been little studied, but contain information about th…
The infrared spectra of very large, compact, highly symmetric, polycyclic aromatic hydrocarbons (PAHs)
Charles W. Bauschlicher, Els Peeters, Louis J. Allamandola
The mid-infrared spectra of large PAHs ranging from C54H18 to C130H28 are determined computationally using Density Functional Theory. Trends in the band positions and intensities a…
The 15-21 um PAH plateau
E. Peeters, A. L. Mattioda, F. Kemper +2
We present 14--21 um emission spectra of star forming regions and compare them with the PAH spectra from the Ames PAH database. We show that while the emission in this region can b…
The profiles of the 3 to 12 m PAH features
B. van Diedenhoven, E. Peeters, C. Van Kerckhoven +4
We present spectra of the 3.3 m and 11.2 m PAH features of a large number of (extra-) galactic sources, obtained with ISO-SWS. Clear variations are present in the profiles of…
The Role of Polycyclic Aromatic Hydrocarbons in Ultraviolet Extinction. I. Probing small molecular PAHs
Geoffrey C. Clayton, Karl D. Gordon, Adolf N. Witt +7
We have obtained new STIS/HST spectra to search for structure in the ultraviolet interstellar extinction curve, with particular emphasis on a search for absorption features produce…
The rich 6 to 9 um spectrum of interstellar PAHs
E. Peeters, S. Hony, C. Van Kerckhoven +4
Here, we present 6-9 um spectra of a sample of RNe, HII regions, YSOs, evolved stars and galaxies that show strong unidentified infrared bands, obtained with the ISO-SWS. The IR em…
A New Feature in the Interstellar Extinction Curve at 2700 A: Diamonds in the Rough?
Geoffrey C. Clayton, Karl D. Gordon, Adolf N. Witt +7
Space Telescope Imaging Spectrograph (STIS) and archival International Ultraviolet Explorer (IUE) data were used to search for structure in the ultraviolet interstellar extinction…
The CH out-of-plane bending modes of PAH molecules in astrophysical environments
S. Hony, C. Van Kerckhoven, E. Peeters +3
We present 10-15 micron spectra of a sample of H II regions, YSOs and evolved stars that show strong unidentified infrared emission features, obtained with the ISO/SWS spectrograph…
Direct spectroscopic evidence for ionized PAHs in the interstellar medium
G. C. Sloan, T. L. Hayward, L. J. Allamandola +3
Long-slit 8-13 um spectroscopy of the nebula around NGC 1333 SVS reveals spatial variations in the strength and shape of emission features which are probably produced by polycyclic…
A Survey of Near Infrared Emission in Visual Reflection Nebulae
K. Sellgren, M. W. Werner, L. J. Allamandola
We present a survey for extended 2.2 m emission in 20 new visual reflection nebulae, illuminated by stars with temperatures of 3,600 --- 33,000 K. We detect extended 2.2 m em…
