How is rotational averaging calculated in this program?
When calculating the 2D spectroscopy results using "Exciton Dynamics Lab for Light-Harvesting Complexes (GPU-HEOM) " I notice that rotational averaging is dealt with my calculating results over 4 different runs. Is this an exact averaging or an approximation? Also is there any literature you can point me towards which explains how this works? When I have looked at this problem I have found I require 21 different runs, but I was assuming a general configuration for the polarisations of the beams.
