Direction decides: Magneto-chiral dichroism describes the dependence of the absorbance of a chiral molecule on the direction of a magnetic field to which it is exposed, and it may help to explain the homochirality of life. This phenomenon was now observed in organic compounds using porphyrin J-aggregates.
