Chiral spectroscopy: quality control for twisted molecules
Publicado em 08 abril 2022
It’s not easy to be sure that drugs and supplements with twisted (chiral) structures are turning in the correct direction. Now researchers in the US and Brazil have shown that twirling infrared light can probe both the structures of molecular crystals and their twists, confirming that they are safe and effective.
Walking along the supplement aisle, you might notice that some have an L or D in front of the names. This denotes the direction in which the molecule twists, ie, clockwise (D) [...]
