✦ Synopsis

The difference in the interaction energies of two co-r&at&,, m and two counter-rotating, spherical-top moIecules is of sccond order in the rotational constant B, and not fust order. Co-and counter-spinning alkali-metal atoms exbibzt a simiiar but numerically much larger "chiral" discrimination.

Atkins [I] discussed the effect of the relative rotational motion of two spherical-top molecules upon their dispersion energy. For the difference in the second-order interaction energies of two co-rotating, and two counter-rotating, tops LZ and b he obtained (1) where G(J,,&)= [B,(& -I-1)(2+, +3)+Bb(Jb + l)(W= +3)1&J, + I)@& + I>&, + 1)(2Jb + 1).
