The rotation of a 1H127I molecule can be pictured as the orbital motion of the hydrogen atom at a distance of 160 pm from the stationary iodine atom. Suppose that the molecule rotates only in a plane. Calculate the minimum energy needed to excite the molecule into rotation. What, apart from 0, is the minimum angular momentum of the molecule?
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.
