Figure 2.
Results of polarized absorption measurements of the BN indole derivatives in stretched PE films. (A, B) The experimental absorption spectra (blue) of the external BN indole (A) and the fused BN indole (B) are shown in comparison to fits of these data to Gaussian functions (dashed red curves). Transitions are numbered according to the same scheme as in Table 1. (C, D) The experimental LDr spectra (blue) of the external BN indole (C) and the fused BN indole (D) are shown in comparison to the calculated LDr spectra (dashed red), which are based on the experimental transition moment orientations, intensities, energies, and peak widths obtained from a simultaneous fit to the data shown in (A) and (B), respectively.
