Polycyclic aromatic hydrocarbon (PAH) molecules are essentially graphene in the subnanometer limit, typically consisting of 50 or fewer atoms. With the addition or removal of a single electron, these molecules can support molecular plasmon (collective) resonances in the visible region of the spectrum. Here, we probe the plasmon dynamics in these quantum systems by measuring the excited-state lifetime of three negatively charged PAH molecules: anthanthrene, benzo[ghi]perylene, and perylene. In contrast to the molecules in their neutral state, these three systems exhibit far more rapid decay dynamics due to the deexcitation of multiple electron–hole pairs through molecular plasmon “dephasing” and vibrational relaxation. This study provides a look into the distinction between collective and single-electron excitation dynamics in the purely quantum limit and introduces a conceptual framework with which to visualize molecular plasmon decay.

Ultraviolet Excitation

The Ca I absorption spectrum between 300 and 800 Å (41-10 eV) has been photographed revealing at least 125 new lines. All the stronger lines are identified by comparison with Hartree-Fock calculations. In addition to single electron excitation of the 3p-subshell there is clear evidence of a simultaneous excitation of the 4s valence subshell and a 3p-subshell electron. The more important processes of multi-electron excitation are indicated. The general case of 3p → 3d excitation in elements Z ═ 18 to 28 is discussed and is illustrated by plots of the effective central potentials for 3d wavefunctions derived from the Hartree-Fock results.
