Photoinduced optical rotation in a racemic mixture of hydrogen peroxide molecules

摘要

A problem of inducing a required sign of chirality in a racemic mixture ofenantiomers of a chiral molecule is analyzed. As an example, a racemic mixture(vapor) of left- and right-handed enantiomers of hydrogen peroxide (H2O2)molecule is considered. It is shown that biharmonic Raman excitation of thesplitted due to the left-right conversion internal rotation levels can beeffectively used for inducing optical activity in the initially racemic vaporof H2O2 molecules. An experiment to study this photoinduced optical rotation isdiscussed.
