The J = 2 → 3 pure-rotational transition for the ground vibrational state of 3ºK³7C1 occurs at 22410 MHz. Neglecting centrifugal distortion, predict the frequency of the J = 0 → 1 pure-rotational transition of (a) 3ºK³7C1, and (b) 3ºK³C1. You may use the mass numbers as the masses of the corresponding atoms expressed in amu.
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.
