Abstract:
We have investigated the electronic excitation spectrum of individual manganese phthalocyanine (MnPc) molecules in a coronene matrix. Our results corroborate that the observed excitation spectrum is rather sensitive to oxygen contamination of the respective samples. Annealing in vacuum allowed the determination of the electronic excitations of individual MnPc molecules. These results confirm previous data from the literature and, in addition, we have identified a low energy excitation at about 0.8 eV, which had not been reported before.

Electron Affinity
Electron Behavior
Electrons are negatively charged subatomic particles that are attracted to an orbit around the positively-charged nucleus of an atom. They reside in locations that are associated with energy levels called shells and are further organized into sub-shells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the...
