Description

High resolution quasielastic neutron scattering experiments on the crystalline phase of terephtal-bis-butyl aniline (TBBA) are reported. The data are discussed in terms of rotational motion of the butyl chain extremities. Best agreement with the experiment is obtained assuming that be last methylene and methyl groups are rotating. Both correlation times and activation energy are consistent with previous NMR work on solid substances containing alkyl chains

Abstract (French)

On rapporte des experiences de diffusion quasi elastique de neutrons, a haute resolution, dans la phase solide du terephtal-bis-butyl aniline (TBBA). Celles-ci revelent que les extremites des chaines butyle se reorientent rapidement. Les meilleurs resultats sont obtenus en supposant une rotation des derniers groupes methylene et methyle des chaines. Les valeurs des temps de correlation et de l'energie d'activation sont compatibles avec celles, obtenues par RMN dans des substances solides contenant des chaines aliphatiques
