Calculate the fundamental vibrational wavenumber of carbon monoxide, considering it to behave like a harmonic oscillator with a force constant 1902.5 Nm. By how much will this wavenumber change if the molecule contains the isotope BC instead of the more abundant 12C? Use m 12u for 1C, m 13u for 13C and m=16u for 160.
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.
