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.

Model of Coupled or Dissociated Eye-Head Coordination

Journal of Vestibular Research, 1994
Tight coupling between eye and head movements have been observed in response to a single visual target offset or a single flash. On this basis, when the visual stimulus consists of two successive steps or flashes in the same (horizontal) direction, either increasing in eccentricity or decreasing in eccentricity, gaze should be due to concomitant eye ...

Bimanual Coordination and Coupled Oscillations

2020
The study of bimanual rhythmic finger movements was among the first problems investigated in dynamical cognitive modeling (HKB model). The phase transitions that can occur with increasing movement frequency are explained on the level of a movement potential.

Metal-mediated coupling of a coordinated isocyanide and indazoles

Dalton Transactions, 2013
A reaction between equimolar amounts of cis-[PdCl2(CNCy)2] (1) and indazole (HInd, 2) or 5-methylindazole (HInd(Me), 3) proceeded in refluxing CHCl3 for ca. 6 h affording the aminocarbene species cis-[PdCl2{C(Ind)=N(H)Cy}(CNCy)] (4) or cis-[PdCl2{C(Ind(Me))=N(H)Cy}(CNCy)] (5) in good (72-83%) isolated yields.

Coordinated behavior between visually coupled dyads

Proceedings of the 2nd Augmented Human International Conference, 2011
We describe how visually coupled people start their synchronized behavior with two visual coupling conditions: view-swapping and view-blending. In the view-swapping condition, two people's views are changed from the first-person perspective so that both see their partner's views. The view-blending condition allows people to see the blended view of both

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 ...

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.

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.

Coupled Oscillators and Normal Coordinates

American Journal of Physics, 1967
Two blocks and three heavy springs are coupled together and made to oscillate on an air track. The motion of one of the blocks is recorded by means of a spark timer. With arbitrary initial conditions, the motion is complicated. From the masses of the blocks and the springs and from the spring constants, one then calculates theoretically the normal ...
