We have isolated the magnetochiral refraction in Pasteur's tartrates and deduced the associated magnetochiral absorption. The presence of a strong peak at 235 nm in the magnetochiral absorption spectrum of tartrates shows that Pasteur's first attempt to induce chirality with a magnetic field could perhaps have succeeded, provided that a UV source was simultaneously used. To cite this article: T. Ruchon et al., C. R. Physique 5 (2004).

Nous avons isolé l'interaction magnétochirale en réfraction dans les tartrates étudiés par Pasteur, et en avons déduit l'absorption magnétochirale. La présence d'un pic important à 235 nm dans le spectre d'absorption magnétochirale montre que les tentatives de Pasteur pour induire de la chiralité à partir d'un champ magnétique auraient peut-être pu aboutir s'il avait utilisé simultanément une source UV. Pour citer cet article : T. Ruchon et al., C. R. Physique 5 (2004).
