4-phenylene oxide) (PPO). Theresults show that the rotation of the methyl groups in solid PPO is partially restricted
whichresults in a surprisingly efficient spin diffusion between the aromatic proton and methyl protoncharacterized by a diffusion time of 150μs. The results also show that the aromatic ring insolid PPO is rigid and twisted
which causes all aromatic carbons to be chemicallyunequivalent.
Abstract
Experiments including

C spin-lattice relaxation
13
C heteronuclear dipolar dephasing and
1
H spin diffusion are performed on poly (2

4-phenylene oxide) (PPO). Theresults show that the rotation of the methyl groups in solid PPO is partially restricted
whichresults in a surprisingly efficient spin diffusion between the aromatic proton and methyl protoncharacterized by a diffusion time of 150μs. The results also show that the aromatic ring insolid PPO is rigid and twisted
which causes all aromatic carbons to be chemicallyunequivalent.
