www.imperial.ac.uk2. Avoiding the Solution of the Schrödinger Equation The Hamiltonian operator (Equation 2) consists of single electron and bi-electronic interactions – i.e. operators that involve on the coordinates of one or two electrons only. In order to compute the total energy we do not need to know the 3N dimensional wavefunction.
Lecture 6 Quantum mechanical spin - University of Cambridge
www.tcm.phy.cam.ac.ukLast lecture, we saw that the electron had a magnetic moment, µ orbit = − e 2me Lˆ, due to orbital degrees of freedom. The intrinsic electron spin imparts an additional contribution, µ spin = γSˆ, where the gyromagnetic ratio, γ = −g e 2m e and g (known as the Land´e g-factor) is very close to 2. These components combine to give the ...
