Oscillator strength associative

Studies of nonlinear optical phenomena in conjugated polymers date back to the earliest studies of the polydiacetylenes [219], The large oscillator strength associated with the p-p transition gives rise to a relatively large linear electronic polarizibility. The early work speculated that because of the implied delocalization of charge in the excited state, conjugated polymers would offer opportunities as NLO materials.

In the scheme where one level, S2, associated with an oscillator strength interacts with a sparse manifold /, the intensity carried by each of the resulting discrete states ipn is proportional to the squared coefficient a 2, where a is defined by Eq. (9). These discrete states are broadened by interaction with the remaining dense manifold and a Lorentzian line shape Ln(E) of the form Eq. (10) is assumed for each broadened line. Note that these lines are still associated with the same intensities a" 2, that is...
