1-A:-Calculate the energy and wave-length of the photon absorbed when a "Hg"Cl molecule (r. 2.23°A) makes the rotational transition J-0-J-1 and J-1->J=2. B:- In what region of the electromagnetic spectrum are these lines found? 2- Suppose that the equilibrium separation in the 'H"CI molecules is the same and equal to 1.27°A. Compute for each molecule A:-The constant 13. B:- The energy of the first two excited rotationa levels. C:-The frequencies and wave length corresponding to the transition J-0-J-1 and J-1-J-2.
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.
