Fig. 5.6. Simulated emission spectra of VFP-based FRET pairs in a non-FRET situation (black line) and a FRET situation (grey line). Shown are SBFP2-EGFP, E = 14% (A), SCFP3A-SYFP2, E = 24% (inset shows ECFP-EYFP, E - 12%) (B), SGFP2-tagRFP E = 38% (C), SYFP2-mStrawberry E = 44% (D), mKO-mCherry E = 47% (E). The FRET situation assumes a distance of rDA = 6.5 nm between donor and acceptor and uses a 1 1 stoichiometry between donor and acceptor. Excitation at the indicated wavelength, other parameters from Table 5.1.

A chemical mechanism is the set of chemical reactions and associated rate constants that describes the conversion of emitted species into products. From the point of view of tropospheric chemistry, the starting compounds are generally the oxides of nitrogen and sulfur and organic compounds, and ozone is a product species of major interest. Chemical mechanisms are a component of atmospheric models that simulate emissions, transport, dispersion, chemical reactions, and removal processes (Seinfeld, 1986, 1988). 

Simulated emission A light amplification by stimulated emission of radiation (LASER) operates in systems where a nonequilibrium distribution of energies is created by a pump that induces transition to a higher excited state. As a result, the emission of some radiation is made to stimulate a cascade of emission. This emission will stop when the equilibriiun to the population of energy states is returned.

From quantum mechanical theory, the electron-transition description is shown in Fig. 6.3b containing the absorption, self-emission, and simulated emission processes [13]. The electron energy takes discrete values in a single atom as indicated by m and n. The light absorption and emission in these two quantum states can be described by statistical methods, and the energy relation between the w-th and n-th quanmm states in the absorption and emission processes is expressed as Scs/nn = Em — E . Under the light irradiation of energy-density p wmn), die...

The simulated differential emission rate for 2-phenylftiran computed with Eq. (34) is shown in Fig. 5, together with experimental data from Ref. [16]. The simulated emission was computed with Eq. (34). The numerical-integration error (gray area) was computed with an expression similar to Eq. (25), but for the differential emission rate. Parameters are given in Table 4. All hnes were assumed to have the same width (5 . An ensemble of 850 points was built around the minimum of the Si state assuming T = 0 K.

Laser is an acronym for light amplification by simulated emission of radiation. In SERS, as well as in other types of Raman scattering experiments, a continuous-wave (CW) gaseous ion laser is normally used, e.g., an argon-or krypton-ion laser. It is also possible to use a pulsed laser, such as a neodymium, Nd ", in yttrium-aluminum garnet (YAG) laser however, a much...
