Electronic Absorption Spectra of Neutral Perylene (C20H12), Terrylene (C30H16), and Quaterrylene (C40H20) and Their Positive and Negative Ions: Ne Matrix-Isolation Spectroscopy and Time-Dependent Density Functional Theory Calculations

Autor: Farid Salama, Martin Head-Gordon, Jennifer L. Weisman, R. Ruiterkamp, Thomas M. Halasinski, Timothy J. Lee

Publikováno v: The Journal of Physical Chemistry A. 107:3660-3669

We present a full experimental and theoretical study of an interesting series of polycyclic aromatic hydrocarbons, the oligorylenes. The absorption spectra of perylene, terrylene and quaterrylene in neutral, cationic and anionic charge states are obt

Polycyclic Aromatic Hydrocarbons (PAHs) are thought to be the carriers of the ubiquitous infrared emission bands (UIBs). Data from the Infrared Space Observatory (ISO) have provided new insights into the size distribution and the structure of interst

Electronic Absorption Spectra of Neutral Pentacene (C22H14) and Its Positive and Negative Ions in Ne, Ar, and Kr Matrices

Autor: Farid Salama, Douglas M. Hudgins, Thomas M. Halasinski, Louis J. Allamandola, Thomas Bally

Publikováno v: The Journal of Physical Chemistry A. 104:7484-7491

The absorption spectra of neutral pentacene (C22H14) and its radical cation (C22H14+) and anion (C22H14-) isolated in solid Ne, Ar, and Kr have been measured from the ultraviolet to the near-infrared. The associated vibronic band systems and their sp

Matrix Isolation and Cold Diffusion of Mass-Selected CS2•+ in Neon: Infrared Observation of the Asymmetric Stretch of CS2•+ and CS2•

Autor: George E. Leroi, Jerry T. Godbout, and John Allison, Thomas M. Halasinski

Publikováno v: The Journal of Physical Chemistry. 100:14865-14871

Vibrational spectroscopic characterization of neon matrices in which mass-selected CS2•+ and CS•+ were deposited reveals absorptions due to (ν3) CS2•+ (1207.1 cm-1) and (ν3) CS2•- (1159.4 cm-1). The results are compared to previous CO2•+

Matrix Isolation of Mass-Selected Cations: Are Counterions Present and How Are They Formed?

Autor: John Allison, and George E. Leroi, Thomas M. Halasinski, Jerry T. Godbout

Publikováno v: The Journal of Physical Chemistry. 100:2892-2899

It has been demonstrated that sufficient numbers of mass-selected cations can be directly deposited into growing inert gas matrices at low temperatures for spectroscopic analysis. However, the mechanism that must exist to maintain electrical neutrali
