Experimental evidence of magnetochiral interaction in Pasteurʹs tartrates

We have isolated the magnetochiral refraction in Pasteurʹs 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 Pasteurʹs first attempt to induce chirality with a magnetic field could perhaps have succeeded, provided that a UV source was simultaneously used.
