چکیده
Interplay between the vibronic and spin-orbit coupling in the ͑⌫ 8 + ⌫ 9 ͒ ϫ ͑g +2h͒ Jahn-Teller problem, where ⌫ 8 and ⌫ 9 are the quartet and sextet spin representation, and g and h denote the fourfold and fivefold degenerate vibrational modes in icosahedral symmetry, respectively, is studied. A 4d 9 or 5d 9 transition-metal ion in an icosahedral field may provide a realization of this system.

Study of strong R–P and spin–orbit vibronic coupling effects in linear triatomic molecules
The vibronic coupling between P and R electronic states of a linear molecule is considered with the inclusion of the spin–orbit coupling of the P electronic state, employing the microscopic (Breit–Pauli) spin–orbit coupling operator in the single-electron approximation. The 6 · 6 Hamiltonian matrix in a diabatic spin-electronic basis is derived by an expansion of the molecular Hamiltonian in po...

The vibronic and spin-orbit-induced interactions among the (3)Sigma(-), (1)Delta, and (1)Sigma(+) electronic states arising from a half-filled pi orbital of a linear triatomic molecule are considered, employing the microscopic (Breit-Pauli) spin-orbit coupling operator. The 6 x 6 Hamiltonian matrix is derived in a diabatic spin-orbital electronic basis set, including terms up to fourth order in...

The laser excited, jet-cooled Ã2E′′ − X̃2E′ electronic spectrum of the silver trimer yields detailed information about its Ãand X̃-state vibronic structure. Following extensive parameter fitting, the absorption and emission spectra are simulated and the bands are assigned. The JahnTeller analysis includes both linear and quadratic coupling terms, considered simultaneously with spin-orbit coupling...
متن کاملIntersystem crossing driven by vibronic spin-orbit coupling: a case study on psoralen.
For 7H-furo[3,2-g][1]benzopyran-7-one (psoralen), intersystem crossing (ISC) rate constants have been computed. Employing the Fermi golden rule, the harmonic approximation, and a pure-spin Born-Oppenheimer basis, both direct and vibronic spin-orbit (SO) coupling has been taken into account. Necessary data on electronic excitation energies and potential energy hypersurfaces originate from correl...
متن کاملTopological characterization of delocalization in a spin-orbit coupling system.
We show that wave functions in a two-dimensional ~2D! electron system with spin-orbit coupling can be characterized by a topological quantity—the Chern integer due to the existence of the intrinsic Kramers degeneracy. The localization-delocalization transition in such a system is studied in terms of such a Chern number description, which reproduces the known metal-insulator transition point. Th...
