Synthetic Organic Photochemistry
The remaining space groups are achiral. Resolved chiral molecules must
crystallize in chiral space groups, but a racemic compound may aggregate to
form either an achiral racemic crystal or undergo a spontaneous resolution in
which the ...

Then in Section 6.713, we consider the reaction of achiral starting materials
reacting in a chiral environment—in this case in the presence of a chiral catalyst.
We shall see that an enantiomerically pure product may be produced from achiral

Organic Chemistry: A Short Course
Now, if the substance is achiral, then for every single molecule in one
conformation that rotates the plane of polarization in one direction, there will be
another molecule with the mirror-image conformation that will rotate the plane of
polarization ...
