Electronic Transitions and Spectroscopy
The term “electronic” connotes electron, and the term “transition” implies transformation. In a molecule, the electrons move from a lower to a higher energy state due to excitation. The two energy states, the ground state and the excited state are the lowest and the highest energy states, respectively. An energy change is observed with this transition, which depicts the various data related to the molecule.
Photoelectron Spectroscopy
Photoelectron spectroscopy (PES) is a part of experimental chemistry. It is a technique used in laboratories that involves projecting intense beams of radiation on a sample element. In response, the element ejects electrons for which the relative energies are measured.
List and define the various energy terms that contribute to the Hartree-Fock energy of an atom or molecule.
the Hartree–Fock (HF) is a method of approximation to the determination of the wave function and the energy of a quantum many electron system in a stationary state.
various energy are involved in contributing the Hartree-Fock energy of an atom or molecule for many electron system.
in this method the full molecular wave function is a function of the coordinates of each of the nuclie, in addition to those of electrons.
