With important contributions from many Williams undergraduates over recent years, we have completed a series of high-precision spectroscopic measurements in Group III and IV atoms such as thallium, indium and lead. These results test state-of-the art theoretical models of these complicated atoms and guide further refinement. I will discuss some recent results including a new precision measurement of a “forbidden” transition in lead which makes use of a laser polarimetry technique capable of microradian optical rotation resolution. Improved models of these heavy atoms aid in the bigger goals of testing the Standard Model (and beyond) with table-top atomic and laser physics experiments.
