Practical Thermochemistry-Na Metal Cl Gas and Solid NaCl

... parameters of a solid to such a precision that the corresponding residual pressure would go to something in the order of 1 bar. For example the above geometry optimization for solid NaCl leads to a residual pressure of 720 bar. A very precise geometry optimization using 500eV cutoff and a 11x11x11 k ...

Highly fluorescent silver/gold mixture quantum clusters showing

... The quantum yield is determined using the comparative method, which relies on the use of fluorescence standards with known fluorescence quantum yields (Rhodamine 6G; QY=95% in our case). We use the equation: QYx=QYs * [Ax/As]*[Fs/Fx]*[nx/ns]2 where Ax and As are the integrated area under the correct ...

... No two electrons in an atom can ever have the same set of values for the set of quantum numbers n, l, ml, and ms. • The Pauli exclusion principle explains the electronic structure of complex atoms as a succession of filled levels with different quantum numbers increasing in energy, where the outermo ...

Why do we get an exponentially decreasing probability of populating energy levels (eg. homework #1 and examples in class) when we are following the fundamental postulate of statistical mechanics, which says something about assigning equal probabilities to each microstate? In other words, why don’t t ...

... Department of Physics, Colorado School of Mines, Golden, Colorado 80401, USA (Received 22 May 2007; published 14 November 2007) The N-body problem in a tilted double well requires new features for macroscopic quantum superposition in ultracold atoms. In particular, one needs to go beyond the single- ...

Franck–Condon principle



The Franck–Condon principle is a rule in spectroscopy and quantum chemistry that explains the intensity of vibronic transitions. Vibronic transitions are the simultaneous changes in electronic and vibrational energy levels of a molecule due to the absorption or emission of a photon of the appropriate energy. The principle states that during an electronic transition, a change from one vibrational energy level to another will be more likely to happen if the two vibrational wave functions overlap more significantly.
