The first is the coherent excitation transfer process, which gives rise to the Lorentz–Lorenz shift. Giga-fren The results are fully consistent with previously determined cross sections for excitation transfer in other binary metallic vapor systems.

The excitation-transfer process is not limited to a single emotion. Excitation transfer theory posits that the physiological dimension of one's emotional response to an initial stimulus or event persists or lingers beyond the immediate exposure to that stimulus. Triplet excitation energy transfer (TEET) involves an exchange of two electrons of different spin and energy; thus, it is like an overlap interaction of two pairs of MOs. A model of excitation transfer was advanced, based on the assumption that salient elements of excitation decay relatively slowly, and that interoception of excitation is nonspecific, permitting the integration of any residue with elements of the excitatory response to subsequent stimuli. Abstract Previous research of excitation transfer theory (e.g., Zillmann, 1971; Zillmann 1983), has long since demonstrated that, under certain time-critical conditions, residual physiological excitation remains localized and the EET is named incoherent; in the contrary case the excitation may move as a delocalized state through the aggregate, i.e. the EET is a coherent transfer Excitation and charge transfer are fundamental processes in nature, and controlling these processes is a major goal of quantum chemistry. While these processes are well understood for the usual free-space case, when the electromagnetic vacuum is changed due to, e.g., a cavity, these processes can be dramatically different.

Excitation Transfer in the Core Light-Harvesting Complex (LH-1) of Rhodobacter sphaeroides: An Ultrafast Fluorescence Depolarization and Annihilation Study. Stephen E. Bradforth, Ralph Jimenez, Frank van Mourik, Rienk van Grondelle, and ; Graham R. Fleming

The source of excitation can be anything, from watching a horror movie to doing physical activities such as sports. excitation remains localized and the EET is named incoherent; in the contrary case the excitation may move as a delocalized state through the aggregate, i.e. the EET is a coherent transfer (Redirected from Excitation Transfer) Excitation-transfer theory purports that residual excitation from one stimulus will amplify the excitatory response to another stimulus, though the hedonic valences of the stimuli may differ. The excitation-transfer process is not limited to a single emotion.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. The B800 to B850 excitation transfer occurs with a 650 fs time constant. The depolarization of B850 emission follows a wavelength dependent, biexponential decay with time constants 50−90 and 400−500 fs. accruing arousal and hence make the person all the more vulnerable to transfer effects in his postcommunication behavior. (Tannenbaum & Zillmann, 1975, p. 187) This opening quote provides the rationale for the application of excitation transfer theory to the study of mediated stimuli, and past media research has lent much credence to Tannenbaum

Se hela listan på exploringyourmind.com The excitation-transfer effect is the result of misattributing excitement to a person, not its real cause, and misinterpreting it to falling in love or liking someone very much. When it happens, people mistakenly think they like someone, when they really do not. Q: Why do we fall in love with certain people?

30 nov. 2016 — Due to nonlinearities, different excitation levels may affect the transfer function in low frequencies which was shown in an experimental study.

The excitation-transfer theory purports the idea that residual excitement from one stimulus can amplify the excitatory response created by an other stimulus even if those two stimuli are cognitively interpreted as different emotions. For instance, the anger or fear (adrenaline action) that might be felt while watching All image content sourced from google search engine.

16 Apr 1999 Theory of excitation transfer in the intermediate coupling case is proposed. This theory is appropriate to such molecular systems where the 

For over three decades, excitation transfer theory has been empirically applied to the domain of sexual arousal and attraction (for review, see Foster, Witcher, Campbell, Participants were also asked to rate their seatmates' levels of attractiveness. Consistent with the predictions of excitation transfer theory, for males and females riding with a nonromantic partner, ratings of attractiveness and dating desirability toward the photographed individual were higher among persons exiting than entering the ride. 2019-03-04 · CE between a metal and a ceramic was revealed as electron transfer and its subsequent release is dominated by the thermionic emission process. Here, the release of CE-induced electrostatic charges on a dielectric surface under photon excitation is studied by varying the light intensity and wavelength, but under no significant raise in temperature.
