The effect of solvent viscosity (q8) and temperature (2') on the shape of the concentration dependence of the principal and total recoils in creeprecovery viscoelastometry experiments has been studied for T4 DNA solutions. The range of DNA concentration ( c ) was 2 -40 pg/ml; glycerol, 70-80% v/v, s

The kinetics of folding of the two forms of unfolded ribonuclease A have been measured as a function of solvent viscosity by adding either glycerol or sucrose. The aim is to find out if either reaction is rate limited by segmental motion whose rate depends on external friction. The fast folding rea
Three representative diphenyltriafulvenes, 4,4'-dicy.mo-1 ,2-diphenyltriafulvenc (I), hexaphenyltriapentafulvalene (II) and IO-(3,3diphenylcyclopropenyliden)-anthrone (III) have been investigated. On excitation. the dipole moment of I decreases and reverses sign, i.e., from a value of 7.9 D in the g
