Match each of the following atomic and/or molecular microstates with their definition Translation Rotational Vibrational Electronic Transfer between energy barriers in the scattering zone Periodic motion of atoms in a molecule relative to one another Energy stored as potential energy An incoherent thermically activated process by which electrons move All points of a body moving uniformly in the same direction Movement of all particles associated with a rigid body moving in circles around a common axis
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.
