WebThe hydrogen atom is composed of a positively charged particle, the proton, and a negatively charged particle, the electron. These particles have some intrinsic angular momentum called spin. (However, this spin is not an actual physical rotation; it is, rather, a quantum mechanical effect.) WebWe will have to include the spin of the electron in our calculations now, so we label the hydrogen eigenstates as \ket {n, l, m, m_s} ∣n,l,m,ms . We begin with the fine structure. There are three terms we must consider, which give rise to …

Each hydrogen molecule (H 2) consists of two hydrogen atoms linked by a covalent bond. If we neglect the small proportion of deuterium and tritium which may be present, each hydrogen atom consists of one proton and one electron. Each proton has an associated magnetic moment, which is associated with the proton's spin of 1⁄2. In the H 2 molecule, the spins of the two hydrogen nuclei (protons) couple to form a triplet state known as orthohydrogen, and a singlet state known as para… WebNuclear Spin. It is common practice to represent the total angular momentum of a nucleus by the symbol I and to call it "nuclear spin". For electrons in atoms we make a clear distinction between electron spin and electron orbital angular momentum, and then combine them to give the total angular momentum.But nuclei often act as if they are a single entity … WebThe low lying levels in a hydrogen-like atom are indicated schematically in Fig. 2. 16.
