choose the correct answer Concerning nuclear spin (I), which of the ?following is true a. Spin is due to rotation of the nucleus about its axis. b. Protons have spin, but neutrons do not .c. Spin can only have integer or half- integer values. d. Another name for spin is "precession". Prolate shape of nucleus means it has an electric quadrupole moment Q a. Q is +ve b. Q =0
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.
