✦ Synopsis

The rotational dlffuslon behavior of tetracene was used to probe the Internal y~scos~ty of sodium dodecyl sulfate nacelles m the presence of several n-alcohols (C,-Cs)

Fluorescence amstropy of tetracene was measured usmg frequency-domam spectroscopy Several solutions were studled which contamed appromately the same number of alcohol molecules per nucelle The results indicate that, whale the ad&tlon of alcohol allows tetracene to reorient faster wthm the nucelle, the cham length of the alcohol has httle effect on the reonentatlon behavior These findmgs have important rarmficatlons regarding the choux of a mobde phase modtier m mxellar liquid chromatography
