摘要：

A coupled electronic oscillator (CEO) analysis of the third harmonic generation (THG) spectrum for octatetraene is presented. The dominant oscillators and their couplings are identified using tree diagrams. The correspondence between the dominant oscillators in the CEO picture and the relevant excited states in the sum-over-states (SOS) description is demonstrated. The important channels in the SOS are related to the dominant oscillator pathways in the CEO picture. (C) 1996 American Institute of Physics.
