Abstract
We present results for the splay and bend constants, K11 and K33, in two homologous series of nematic compounds, the alkyl- and alkoxy-cyanobiphenyls, and in PAA. They have been obtained in two laboratories using different methods, and the extent to which they agree gives confidence that neither set is significantly affected by systematic error.
Résumé
Nous présentons des résultats concernant les constantes de Frank K 11 et K33 de composés nématiques appartenant à deux séries homologues, les alkyl- et alcoxy-cyanobiphényles et celle du PAA. Ces résultats ont été obtenus dans deux laboratoires par des méthodes différentes. Leur concordance suggère qu'aucun d'entre eux n'est affecté d'erreurs systématiques.
