Question

Because of conservation of angular momentum, there are certain selection rules for determining whether a particular transition between atomic states is allowed. There are two rules:

change in L=+/- 1,
Change in mL=0, +/-1.

Any transition that does not meet these requirements is called a forbidden transition and will not occur.


In the Zeeman effect, the energy levels of hydrogen are split by a magnetic field. Each state with a different value of m_l has a different energy. The differences in energy between adjacent values of m_l are all equal. The Zeeman effect is observed as a splitting in the spectral lines of hydrogen in the presence of a magnetic field. What is the greatest number of lines that a single spectral line can be split into by a magnetic field?
