Superatomic Rydberg State Excitation
SSRN Electronic Journal, 2021Superatomic molecular orbitals (SAMOs) have symmetries (angular quantum numbers) similar to those of atoms, and thus, it is possible to realize Rydberg state excitations (RSEs) in superatomic molecules. In this Letter, the feasibility of superatomic Rydberg state excitation (SRSE) is explored using gold superatoms based on first-principles calculations.

Polysilane excited states and excited state dynamics
Chemical Physics, 1990Abstract Femtosecond time-resolved excited state absorption spectroscopy is used to reveal excited states of linear-chain poly(di- n -hexylsilane) about 1 eV and in the range of 3.5 eV above the lowest excited state. A description of the excited state dynamics following optical excitation in polysilanes is presented. The concept of conjugation length

This chapter provides a general overview of photochemistry and photophysics, starting with photochemical processes in everyday life and the nature of light. Then, a discussion about formation of electronic excited states by light absorption is presented together with their deactivation processes.

Topical Meeting on Multiple Excitations of Atoms, 1986
Doubly excited atoms, with two excited electrons, occur both above and below the first ionization limit. The interactions between the doubly excited states and the energetically similar singly excited channels are manifested by autoionization and series perturbations in these two cases.

Electronic Excited‐State Engineering
ChemPhysChem, 2008Long-living complexes: A CuI- bisphenanthroline complex exhibits a 15-fold prolongation of its excited state lifetime due to the planned intervention of an appended anthracene fragment (see picture). This elegant example of electronic excited-state engineering extends the range of possibilities for improving the photophysical properties of CuI ...

Excited-State Lattice Dynamics
Europhysics Letters (EPL), 1993The transient dynamics of a bound electron in a crystal, linearly coupled to the lattice and excited by femtosecond light absorption, is studied in the presence of the whole phonon spectrum and of a complex electron structure. Use is made of a numerical method which allows the evaluation of the resulting non-linear dynamics.

Excited-State Acid−Base Chemistry: Evidence for a Dissociative Excited State
Inorganic Chemistry, 2003Excitation (410 nm) of the bimetallic [(bpy)(2)Ru(CN)(mu-CN)Rh(NH(3))(4)Br](2+) produces the MLCT state localized on the (bpy)(2)Ru(CN)(2) ligand. Photoinduced cleavage of the bimetallic occurs in the presence of [H(+)], and the dependence yields a K(a) equivalent to that for ground-state cis-(bpy)(2)Ru(CN)(2) implying separation of the bimetallic ...

Excited states of128Ba have been investigated via the118Sn (13C, 3n) reaction by means of inbeam gamma spectroscopy. 28 new levels and several spin and parity assignments were established, revealing the existence of two superbands and a tentative new negative parity band.
