where ω L = E L /ℏ. From this system of ODEs, we note that the dipole angle, θ, adds a phase to the circularly polarized field acting on the linear exciton, with the coefficient evolving as c L (t). When the same pulse interacts with the linear chromophore, the equal-magnitude x and y components of the field interact with the components of the dipole vector separately, weighted by the relative angle of the dipole, θ, as described by Equations 5 and 6.
