| Description | Citation typed |
| Citation | Mason's work centres on chiroptical properties of organic and coordination compounds. He made, in 1962, the first non-empirical determination of absolute configuration by measurements of circular dichroism on the alkaloid calycanthine. He explained and illustrated in many examples both in organic and coordination chemistry the association of rotatory power with chromophores admitting suitable combinations of electric and magnetic dipole transitions. His new ligand-polarization model complements the crystal-field model, and is superior to it in dealing successfully with an important class of cases that hitherto seemed anomalous, such as the absolute value and temperature dependence of the d-d dipole strengths in tetrahedral transition metal complexes. |
