a. 3. Now you have an isolated system consisting of two charged species of the same sign. How do you think an electrostatic force would change with respect to distance between two charged species of the same sign? (Reflect back to the electric field hockey simulation if needed). X an g command N M b. Explain in words what is happening to the potential energy as the two charged species of the same sign move together. Why does the potential energy change in this way? c. After examining the axes below, now draw a graph to show how the potential energy of the system changes with distance between the two charged species of the same sign. (Hint: Where would objects at a great distance be located on your distance axis? This is the starting point.)

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.
