2. 3), -2.40 (br s, H, pyrrole H at naphthalene site), -4.05 (br s, H, pyrrole H at benzene site). Since, as shown in Fig. 1, UV-VIS absorption, MCD and especially CD spectra change depending on the solvent the details of these spectra will be reported in a full paper.

10. In the absence of aggregation, the shapes of the CD spectra of allowed transitions are similar to that of the electronic absorption spectrum, aside from its sign (W. Moffitt and A. Moscowitz, J. Chem. Phys., 1959, 30, 648).
