23. Due to a modification of our fitting routine, as well as additional data, some of the lifetime values reported in Ref. 4, Fig. 4, (ethane solvent only) have been changed, particularly those at 34°C. This does not significantly alter the nature of the plateau region observed in Ref. 4, but rather shifts the lifetimes to longer times. The lifetime at 5 mol/l is ∼30 ps longer and the lifetime at 12 mol/l is ∼20 ps longer. The values between these two densities are ∼10 to ∼15 ps longer. The result is to make the plateau in the lifetime with density that occurs around the critical density slightly less flat on the low density side, and somewhat flatter on the high density side. The data point in ethane at 5 mol/l and 50°C has a shorter lifetime by 25 ps than is reported in Ref. 4. The reduction in lifetime brings this point more in line with the other 50°C data reported in Ref. 4. The other points at 50°C are essentially unchanged.
