However, the breadth of possible configurations and experimental parameters makes general modeling of an experiment difficult.

One challenge is that many atomic energy levels consist of numerous magnetic sublevels that arise from the different possible orientations of the electron's and nucleus's angular momentum.

These sublevels have different responses to applied magnetic and electric fields which leads to measureable differences for most real-world atomic sensors.

This reduction in dimensionality gives a fundamental improvement to the time complexity of the calculation (over an order of magnitude) while simultaneously returning higher accuracy results.
