An algorithm is employed to retrieve the differential bond polarizabilities of the C‐C bonds from the Raman optical activity (ROA) spectrum of (−) α ‐pinene. (−) α ‐pinene possesses two asymmetric centers (carbon atoms) and a local mirror symmetry. These differential bond polarizabilities show the characteristics of the asymmetry around the asymmetric carbons with respect to the mirror reflection. This analysis is accompanied along with the ROA mode signatures and the calculated β ( G ') 2 and β ( A ) 2 which show the ROA coupling mechanisms involving the electric/magnetic dipoles and the electric dipole/quadrupole, respectively.
