The Lyman series of the hydrogen atom represents transitions from the electronic energy level n to the energy level n=1. (i) Derive a formula that relates (a) the transition energy, Aɛ, and (b) the wavelength, λ, of the emitted photon to the quantum number of the upper energy level n. (ii) Calculate the expected wavenumber, , for the first 4 transitions in the Lyman series.
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.
