Hi. I did an esr-experiment, analyzing hydrogen and deuterium. I am wondering: Why do the atoms not have the same g-factor?

ESR (Electron Spin Resonance) spectroscopy is a technique used to study the electronic structure and properties of molecules. It involves the measurement of the energy changes associated with the transition of electrons between different spin states in a magnetic field.
Hydrogen and deuterium are both isotopes of the element hydrogen, with deuterium having one extra neutron in its nucleus. In ESR spectroscopy, the g-factor (a measure of the electron's sensitivity to a magnetic field) for hydrogen is different from that of deuterium due to their different nuclear magnetic moments.
The g-factor determines the energy level spacing in the ESR spectrum. A higher g-factor means a larger separation between energy levels, resulting in a more spread out spectrum. This can make it easier to distinguish different species in a sample.
ESR spectroscopy can be used to study the electronic structure and properties of hydrogen and deuterium-containing molecules, such as radicals and free radicals. It can also be used to investigate the dynamics of hydrogen and deuterium exchange reactions in biochemical systems.
ESR spectroscopy is unique in its ability to study molecules with unpaired electrons, such as radicals, which cannot be studied using other spectroscopic techniques. It also provides information about the spin state and magnetic properties of these molecules, which is not obtainable through other techniques.
