Bold characters indicate the wavenumbers of distinctive bands for crystalline
and amorphous phases. Bold and italic characters point out the wavenumbers
of interesting bands observed in the crystalline phase of the COPES 9,7/9-0.5
copolymer.
b
The band is narrow in the crystalline state whereas appears very broad in the
amorphous state.
