An ion beam reflectronÕsingle-photon infrared emission spectrometer for the study of gas-phase polycyclic aromatic hydrocarbon ions: Testing proposed carriers of the unidentified infrared emission bands

چکیده
We describe the design and performance of an electron-impact ion beam reflectron system coupled to our ‘‘single-photon infrared emission spectrometer’’ for measurement of infrared emission from excited gas-phase polycyclic aromatic hydrocarbon ~PAH! cations. This experiment provides for direct comparison of laboratory infrared emission spectra of gaseous ionized PAHs with the ‘‘unidentified infrared emission bands,’’ the origin of which is still debated. © 2003 American Institute of Physics. @DOI: 10.1063/1.1544418#

Single-photon Infrared Emission Spectroscopy of Gaseous Polycyclic Aromatic Hydrocarbon Cations: a Direct Test for Proposed Carriers of the Unidentified Infrared Emission Bands
We describe the measurement of infrared emission from excited gas-phase polycyclic aromatic hydrocarbons (PAHs) cations by an electron-impact ion beam reflectron system coupled to our ‘‘ single-photon infrared emission ’’ (SPIRE) spectrometer. This experiment provides for direct comparison of laboratory infrared emission spectra of gaseous ionized PAHs with the ‘‘ unidentified infrared emission...
متن کاملSingle photon infrared emission spectroscopy of the gas phase pyrene cation: support for a polycyclic aromatic hydrocarbon origin of the unidentified infrared emission bands.
We report the first observation of infrared emission from a gaseous ionic polycyclic aromatic hydrocarbon (PAH), the pyrene cation, over the range of wavelengths spanned by the ubiquitous interstellar unidentified infrared emission bands (UIRs). The complete set of pyrene cation IR emissions is observed, with relative intensities consistent with astrophysical observations, supporting the propos...
متن کاملPeripherally hydrogenated neutral polycyclic aromatic hydrocarbons as carriers of the 3 micron interstellar infrared emission complex: results from single-photon infrared emission spectroscopy.
Infrared emission spectra of five gas-phase UV laser-excited polycyclic aromatic hydrocarbons (PAHs) containing aliphatic hydrogens are compared with the main 3.3 microns and associated interstellar unidentified infrared emission bands (UIRs). We show that neutral PAHs can account for the majority of the 3 microns emission complex while making little contribution to the other UIR bands; periphe...
متن کاملSingle Photon Infrared Emission Spectroscopy: A Study of IR Emission from UV Laser Excited PAHs between 3 and 15 μm
Single-photon infrared emission spectroscopy (SPIRES) has been used to measure emission spectra from polycyclic aromatic hydrocarbons (PAHs). A supersonic free-jet expansion has been used to provide emission spectra of rotationally cold and vibrationally excited naphthalene and benzene. Under these conditions, the observed width of the 3.3-μm (C-H stretch) band resembles the bandwidths observed...
