Abstract
Two-stage kinetics of single-chain collapse was clearly observed by us ing a thinnest capillary-tube cell with a wall thickness of 0.01 mm an d a diameter of 5 mm for dynamic light scattering (DLS) measurements. Two relaxation times, tau(crum) for the crumpled globule state and tau (eq) for the compact globule state, were determined for the first time . Experimental DLS data measured in the coil-to-globule transition wer e compared with theoretical predictions.
