Abstract
The overall symmetry of the envelope functions for the four lowest energy excitonic states in colloidal CdSe quantum dots are assigned using excitonic state-resolved pump/probe spectroscopy. These experiments yield a direct test of the two prevailing approaches to quantum dot electronic structure: the effective mass and the atomistic approaches. The experimental results are in complete agreement with the atomistic approach, whereas the effective mass approach fails to assign the correct electron symmetries for higher excitonic states.
