the fluorescence yields for 1-palmitoyl-2- ( 1'-pyrenedecanoyl ) phosphatidylcholine ( py10pc ) in dmpc bilayers are well fitted by the model both below and above the fluid-gel phase transition temperature ( tc ) and permit the evaluation of the probe diffusion rate ( f ) , which is the frequency with which probes take random steps of length l , the host membrane lipid-lipid spacing .
