What is Hund’s rule?Choice one from below. 1)The lowest energy is obtained if the number of electrons with different spins is maximized. 2)The lowest energy is obtained if the number of electrons with the same spin is maximized. 3)The highest energy is obtained if electrons are only placed in s orbitals. 4)The number of electrons in p orbitals must be half the atomic number Z.
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.
