Resonator Configuration

The time during which nearly resonance configuration (within the energy interval on the order of V j) exists is... 

So far, there are four basic ring resonator configurations that can potentially be used as a vapor sensor, the first three of which are shown in Fig. 6.1. They include... 

We note at this point that, when the two fragments become identical, the charge transfer configurations and the locally excited configurations will have to be replaced by charge-resonance and exciton-resonance configurations, respectively.

Various designs for dye lasers, with different pumping sources and geometries, resonator configurations, and flow systems, have been successfully used to optimize laser performance. 

It is prerequisite to define localized, diabatic state wave fimctions, representing specific Lewis resonance configurations, in a VB-like method. Although this can in principle be done using an orbital localization technique, the difficulty is that these localization methods not only include orthorgonalization tails, but also include delocalization tails, which make contribution to the electronic delocalization effect and are not appropriate to describe diabatic potential energy surfaces. We have proposed to construct the locahzed diabatic state, or Lewis resonance structure, using a strictly block-localized wave function (BLW) method, which was developed recently for the study of electronic delocalization within a molecule.(28-3 1)... 

The proton transfer reaction between ammoniiun ion and ammonia, [H3N- H -NH3]+, has been studied previously,(53, 54, 57) which provide an interesting case for validation of the MOVE model. We use three resonance configurations are to describe the proton transfer reaction in [HsN- H -NHa] ... 

It must also be recognized that after suitably isolating the chromophores, their resonant configuration and polar end groups make their identification by chemical tests difficult. If the chromophores are members of the oxonol family, as proposed here, they can exhibit both an aldehyde moiety and an alcohol moiety at the same time. 

On the reaction of halogen with butadiene both 1,4 and 1,2 addition occur simultaneously. The first step is again the reaction with a positive bromine ion with butadiene in configuration I (or III p. 215) leading to the resonating configurations ... 

Hence, four resonance configurations (two for each dithiocarbamate group) should be used for the correct description of thiuram disulfides. The resultant structure is displayed in Scheme 2. 

In this chapter, we introduce the fundamentals of ring resonator sensors and provide an overview of this novel technology. Various ring resonator configurations are discussed and their sensing performances are compared. The applications of ring resonators in detection of chemical and biological molecules are also described.

Another practical question Is applicability of a complex version of multlconflguratlon SCF to Feshbach resonances. In reference 22 It was pointed out that for a Feshbach resonance at least two configurations must be Included In an SCF calculation, the resonance configuration and one representing the decay channel. For the (2s2p) autolonlzlng states of He, for example, we would need (at least) the trial wavefunction... 

Both of these configurations are clearly strongly polar, and if resonance implied that the resultant configuration was a mixture of the component structures nitrous oxide would show a large dipole moment. In fact, the moment is very small, as would be expected if the two structures, the polarities of which are opposed, contributed nearly equally to the resonance configuration. 

The Lever oscillator [39], Fig. 16, allows the application of series resonance configurations with one-side quartz electrode grounding. Since the effect of parasitic capacitance is minimized and simple shielding is possible, this circuit configuration is especially suited for under-liquid QCM. Besides the series resonance frequency, the series resonance resistance Rs can be measured. For this purpose the Lever oscillator allows a largely transistor current gain-independent measurement of the resistance. An automatic level control provides a signal proportional to Rs.
