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
