Abstract
The doublet band structure evident in the fluorescence excitation and absor ption spectra of aluminum phthalocyanine tetrasulfonate in various hyperque nched glassy solvents is attributed to splitting of the Q-band transition i nto x and y components. The splitting is caused by the ligation of water mo lecules to the aluminum atom which decreases the molecular symmetry. Picose cond relaxation from the Q(y) band to the Q(x) band is evident in the hole burned spectra. (C) 1999 Elsevier Science B.V. All rights reserved.
