Abstract
An optical single-molecule study is reported of a quickly frozen solution o f 2.3,8.9-dibenzanthanthrene (DBATT) in n-tetradecane at 1.4 K. The orienta tion has been measured of several hundreds of DBATT molecules within a conf ocal detection volume of similar to 10 mum(3) as a function of their resona nce frequency in the range of the two 0-0 bands in the fluorescence-excitat ion spectrum. Each band is found to correspond to a distinct distribution o f orientations of DBATT molecules. A particular resonance frequency within a band is not correlated with a specific molecular orientation. (C) 2001 El sevier Science B.V. All rights reserved.
