Energies ground state

The eigenfunctions of the zeroth-order Hamiltonian are written with energies. ground-state wavefunction is thus with energy Eg° To devise a scheme by Lch it is possible to gradually improve the eigenfunctions and eigenvalues of we write the true Hamiltonian as follows ... 

Configuration Interaction (or electron correlation) adds to the single determinant of the Hartree-Fock wave function a linear combination of determinants that play the role of atomic orbitals. This is similar to constructing a molecular orbital as a linear combination of atomic orbitals. Like the LCAO approximation. Cl calculations determine the weighting of each determinant to produce the lowest energy ground state (see SCFTechnique on page 43). 

Mindful of the energy requirement for dispersion of a polysaccharide solute in water, syneresis is the slow, spontaneous separation of liquid from a gel, as the solid phase attempts to return to its energy ground state. This phenomenon is a quality defect, because it foreshadows solute sedimentation. 

Inductive effects of substituents on diradical behavior are most pronounced in the disproportionation reaction. With phenyl ketones, electron-donating substituents in the para position and electron-withdrawing substituents in the y-position enhance the probability for product formation from the diradical intermediate, at the expense of disproportionation. This disproportionation is now seen as a normal, low activation energy, ground state reaction 29>94>. It has been... 

For each of the lowest-energy (ground state) terms in Problem 11-1, determine the possible values of J. Which J value describes the state with the lowest energy ... 

The most widely used theoretical framework for elementary solution and interfacial reactions is activated complex theory (ACT), also referred to as absolute reaction rate theory, or transition-state theory (TST). The term activated complex refers to a high-energy ground-state species formed from reactants, for example. 

The ACT begins by postulating an activated complex for each elementary reaction, the high-energy ground-state species formed from the encounter of reactant molecules. An elementary bimolecular reaction... 

It has not yet been possible to unambiguously assign the photoRh transient that may well be a low energy excited state or an high energy ground state transient.
