Figure 3.

Fluorescence excitation and emission spectra of HPIP in water containing large unilamellar vesicles of DMPC at 23°C. The excitation spectra were recorded observing at 400 (—) and 570 nm (—), and the emission spectrum was recorded exciting at 300 nm. The emission anisotropy, <r> (•), at 23°C also is displayed.
