Energy transferred to electrons

My own research efforts [4] have, for many years, involved taking into account such non-Bom-Oppen-heimer couplings, especially in cases where vibration/rotation energy transferred to electronic motions causes... [Pg.2156]

NES is an elastic and coherent scattering process, i.e., it takes place without energy transfer to electronic or vibronic states and is delocalized over many nuclei. Owing to the temporal and spatial coherence of the radiation field in the sample. [Pg.480]

The two above features which modify the simplest theory extend the range of distances z between the fluorophore and the surface over which the results remain valid, from a minimum of several hundred nanometers without the modifications to less than ten nanometers with them. Those two features are incorporated into the results displayed here. Other refinements, not included here, involve consideration of energy transfer to electron-hole pairs (for metals only at z < 10 nm) and nonhomogeneous atomic field effects (z<0.25 nm). We first assume that the intrinsic quantum yield is 100% then we will modify that assumption. [Pg.300]

According to Eq. (1), the thermodynamic driving force of a PET process increases with the solvent polarity and therefore, photoreactions can be simply switched from energy transfer to electron transfer by changing the solvent [8]. However, back electron transfer (BET) often diminishes the yields of radical ions formed and therefore various efforts have been undertaken to circumvent this energy loss process [14]. Among these approaches two processes have been widely used and will thus be described in more detail. [Pg.271]

Neglecting the effect of electronic excitation on the collision dynamics, assumption (c), is justified if either the energy transferred to electrons is small compared with the exchange of kinetic energy between the atoms (so that the... [Pg.24]

The basic concepts regarding ion-energy, ion-current, relative ion velocity, atomic sizes and orbital electron velocities, energy transferred to electrons is discussed in the subsequent sections. [Pg.10]

Since the proton energy E = 0.5 therefore for protons energy of 1 MeV, energy transferred to electrons T = 0.5 ruevl comes out to be just 11 keV due to ratios of masses of electrons and the velocities of electrons and protons. [Pg.11]

Loading of the control grid circuit as aresult of energy transferred to electrons that do not necessarily reach the grid to produce a DC grid current... [Pg.384]
