Exciton coupling in coordination compounds

Dalton Transactions, 2011
This Perspective reviews the impact of exciton coupling on the spectroscopic properties of coordination compounds. Exciton coupling features arise in electronic absorption and circular dichroism spectra when chromophores are brought into close spatial proximity, for example by coordination to a metal centre.

Intercerebellar Coupling Contributes to Bimanual Coordination

Journal of Cognitive Neuroscience, 2007
Abstract Compared to unimanual task execution, simultaneous bimanual tapping tasks are associated with a significantly reduced intertap variability. It has been suggested that this bimanual advantage is based on the integration of timing signals which otherwise control each hand independently.

Experimental substructure coupling with rotational coupling coordinates

26th Structures, Structural Dynamics, and Materials Conference, 1985
A substructure coupling method based on experimentally measured data, including rotational coupling coordinates, is presented. The required rotational displacements at the interface are determined from the measured trnnslati.ona1 mode shapes by cubic spli.ne interpolation.

Cylindrical Coordinates Coupled Mode Theory

IEEE Journal of Quantum Electronics, 2010
We present a cylindrical coordinates coupled mode formulation for coupling between two degenerate modes of a traveling wave resonator. The resonator is assumed to have rotational symmetry and therefore two degenerate modes propagating in opposite directions.

Coupling dynamics in interlimb coordination.

Journal of Experimental Psychology: Human Perception and Performance, 1993
In 1:1 frequency locking, the interlimb phase difference phi is an order parameter quantifying the spatial-temporal organization of 2 rhythmic subsystems. Dynamical modeling and experimental analyses indicate that an intentional parameter phi psi (intended coordination mode, phi = 0 degrees or phi = 180 degrees) and 2 control parameters omega c ...

Generator coordinate approximation to nuclear electronic coupling

International Journal of Quantum Chemistry, 1988
The Generator Coordinate Approximation (GCA) is the general approximation scheme for molecular systems devised to improve the Adiabatic Approximation (AA). This is achieved by replacing the familiar product-type molecular wave function by a convolution product-like state.

Optimizing Vibrational Coordinates To Modulate Intermode Coupling

Journal of Chemical Theory and Computation, 2016
The choice of coordinate system strongly affects the convergence properties of vibrational structure computations. Two methods for efficient generation of improved vibrational coordinates are presented and justified by analysis of a model anharmonic two-mode Hessian and numerical computations on polyatomic molecules.

Coordinate Mastering Using Optical Coupling

SPIE Proceedings, 1989
For a multi-sensor machine vision system, relating each sensor's measurement to a master gage coordinate system has been a difficult task. This is especially true for sheet metal gaging in the automotive industry where sensors may be separated by four or five meters.

Hetero- and Under-Coordination Coupling

2020
A combination of the hetero- and under-coordination forms a promising means of mediating the bonding and electronic dynamics and properties of a substance as the hetero- and under-coordination enhance each other on the charge entrapment and polarization.

Excitonically Coupled States in Crystalline Coordination Networks

Chemistry – A European Journal, 2017
AbstractWhen chromophores are brought into close proximity, noncovalent interactions (π–π/CH–π) can lead to the formation of excitonically coupled states, which bestow new photophysical properties upon the aggregates. Because the properties of the new states not only depend on the strength of intermolecular interactions, but also on the relative ...
