Energy state, of hydrogen atom

We can learn a great deal about the energy states of hydrogen atoms by observing the photons they emit. 

We can learn a great deal about the energy states of hydrogen atoms by observing the photons they emit. To understand the significance of this, you need to remember that the different wavelengths of light carry different amounts... 

It is this last relationship that through replacing it leads to the energy states of Hydrogenic atoms ... 

Excited electronic states have also been considered to explain NR dissociations of heterocyclic radicals in which low-energy losses of hydrogen atoms compete with high energy ring-cleavage dissociations. The latter reactions were interpreted as starting from excited electronic states of the radicals [27,28]. Formation of excited electronic states upon collisional electron transfer has also been studied with smaller molecular systems, e.g. CHn [45], 02 [46], and H3 [47,48],... 

The configuration-interaction representation of the lower-energy states of an atom is the IV-electron analogue of the Sturmians in the hydrogen-atom problem. We choose an orbital basis of dimension P, form from them a subset of all possible A/ -electron determinants pk),k = 0,Mp, and use these determinants as a basis for diagonalising the IV-electron Hamiltonian. It may be convenient first to form symmetry configurations kfe) from the pfe).

NMR (Nuclear Magnetic Resonance) (i> > ) This technique detects the mobility of protons in various energy states. The hydrogen atoms in bound water are at different energy levels than the hydrogen atoms in free water. These energy levels are measured and recorded in the form of NMR spectra. The bound water can be calculated from the NMR spectrum. NMR measurements may be done at any temperature. While NMR may be the most basic method for the measurement of bound water, it requires expensive equipment, trained personnel, and considerable preparation for each experiment. These requirements are not frequently available to the researcher in the paper industry.

The system to be treated consists of two nuclei A and B and two electrons 1 and 2. In the unperturbed state two hydrogen atoms are assumed, so that the zeroth-order energy is 2WH-If the first electron is attached to nucleus A and the second to nucleus B, the zeroth-order eigenfunction is ip (1)

zeroth-order energy, so that the system...
