摘要：
The deconvolution of UV-visible spectra has been carried out for LB films of a merocyanine dye - arachidic acid mixed system in the as-deposited state with a prominent J-band peak, after HT at 90 degrees C without the J-peak, and after heat treatment (HT) at 70 degrees C with a fully developed peak of reorganized J-band. Each spectrum is found to involve three components, Band I, Band H and Band III centered around 510 - 515 nm, 545 - 555 nm and 590 - 600 nm. The dichroic ratios greater than unity for all of the three bands found for the as-deposited films indicate the existence of linkage among the clusters of different aggregation states.
