• These two values of a can, however, be seen to be slightly different, whereas estimation from the n = 1/a 3 relationship gives a ≃ 7.5 Å for both solvents. This slight difference could be explained by the fact that the ratio (Δn)0 (Δε)0/[nbar] may not be the same for the mixture and the pure solvent, which is not the assumption we made

The first characteristic time of the coil can be estimated by extrapolating the results reported by, for polystyrenes with molecular weights of 82 000, 267 000 and 860 000. The characteristic time thus obtained is of the order of 10−7 − 10−8 sec. The life time T of the local nematic order is of the order of 10−7 sec near the transition (see Ref. 22)
