Photoelectron spectra were acquired from a sample of gaseous O2 using X-ray radiation with wavelength 0.99 nmand energy 1253.6 eV. The spectrum contained a large peakfor photoelectrons with speed of 1.57x 107m s-1. Calculate the ionization energy of these electrons. Identify theorbital from which they were most likely emitted.
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.
