Angular Momentum

Part of the Springer Advanced Texts in Chemistry book series (SATC)


In Chapter 1 we saw that one of the areas where strikingly different results are found, compared to the results expected from classical considerations, is associated with the measurement of angular momentum. In particular, the allowed states of orbital angular momentum are quantized at the microscopic level, in sharp contrast to the corresponding classical analog. Also, a new kind of angular momentum, associated with the intrinsic spin of particles, is observed at the microscopic level, which has no classical analog and is also quantized. In this chapter we shall investigate the properties of angular momentum in general, and show how both spin and orbital angular momentum can be considered to be different examples of a general quantum theory of angular momentum.
