- Abstract
- Experimental studies on the natural optical activity and Faraday
rotation of the three different stereoisomers of tartaric acid were
reported recently by Ruchon et al. [Chem. Phys. Lett. 2005, 412,
411]. The authors noted that the Faraday rotation of the meso
(R,S) system differed from those of the (S,S) and (R,R) enantiomers,
and derived a simple dipoledipole interaction model to
describe what they claim to be a new property. We present the
results of both density functional theory (DFT) and coupled cluster
calculations for a structurally elementary model system composed
of two chiral carbon atoms presenting three diastereoisomers
(C2H2Cl2F2), as well as a detailed DFTstudy of the natural
and magnetic-field-induced optical rotation of tartaric acid. The
effects of electron correlation, basis set, and conformational flexibility
are analyzed. It is found that the specific Faraday rotations
of the chiral (R,R) and meso forms of tartaric acid (for lambda=
632.8 nm) differ by about 3%, a value which is quite close in
magnitudebut of opposite signto that obtained with the
simplified model proposed by Ruchon and co-workers (literal)
