Abstract
Nuclear magnetic resonance absorption of stretched Teflon is studied. The second moment of stretched Teflon is calculated on the assumption of all the molecular chains being rotating around the axes of their main chains at room temperature and by the use of the distribution of crystallites determined from experimental results.
Calculated result agrees with experimental result, and rotational transition of this polymer at about room temperature is verified.
Molecular structure in rigid state and molecular motions at other temperatures are briefly discussed.
