Abstract
The absorption spectra of neutral pentacene (C22H14) and its radical cation (C22H14+) and anion (C22H14-) isolated in solid Ne, Ar, and Kr have been m easured from the ultraviolet to the near-infrared. The associated vibronic band systems and their spectroscopic assignments are discussed together wit h the physical and chemical conditions governing molecular anion production in matrices doped with alkali metal (Na or K). TD-DFT calculations were ca rried out to assist in the assignments for the measured spectral features o f the pentacene ions.
