      chain.

AB  - Using a narrowly distributed poly(N-isoporpylacrylamide) (PNIPAM) chain with a 
      degree of polymerization (N) of 3100, randomly labeled with pyrene, we have, for 
      the first time, observed the two-stage kinetics of the coil-to-globule 
      transition. Two characteristic relaxation times, tau(fast) for the crumpling of a 
      random coil (approximately 12 ms) and tau(slow) for the collapsing of the 
      crumpled chain to a compact globule (approximately 270 ms), were measured. To our 
      knowledge, this is the first experimental evidence supporting the two-stage 
      collapsing kinetics of single synthetic polymer chain previously proposed by de 
      Gennes, Dawson, and Grosberg.
