Microwaves show their hand The chirality of a gas phase molecule held in an electric field can be revealed using microwave spectroscopy. Hooking the technique to a separation step might even be exploited to isolate a specific enantiomer from a racemic mixture of both forms. mark for My Articles similar articles

Single catalyst gives two products from racemic mixture Chemists in the US have demonstrated a remarkable reaction in which a single catalyst can transform a racemic mixture - molecules identical in every way except for their chirality - into two distinct enantiomerically pure products. mark for My Articles similar articles
