Left- and right-handed enantiomers (mirror reflections of each other which cannot be superimposed) of a chiral molecule have the same physical properties unless they interact with other chiral objects, such as another chiral molecule and circularly polarized light. Efficient identification and separation of enantiomers are highly demanded in many biological and industrial applications.Bicircular high-harmonic spectroscopy (BHHS) is attracting attention as one of the new, promising chiral discrimination methods. In this study, we numerically analyse the chiral selectivity of BHHS for chiral molecules ranging from a simple one-electron model to L- and D-isomers of alanine, both within and beyond the electric dipole approximation.
