    • From UV-visible spectra, it is difficult to distinguish the transcis isomerization. However, we intend to exclude it in the present case for two reasons. First, the closely packed structure of the film provides little free space for the molecules to undergo isomerization. Second, the IR absorbance of v( C=C) is believed to increase when this isomerization takes place and will result in a kinetics with opposite feature, i.e., first slow because the isomerization should be much faster than oligomerization. The lack of a good isosbestic point in the spectra is considered to be attributed to the experimental error caused by the shift in sample film position in the spectrophotometer because it had to be measured alternatively by UV-visible and IR spectroscopy.
