Chlorine SSNMR of pharmaceutical compounds and their polymorphs

35Cl Solid-State NMR is used to study a variety of solid forms of pharmaceutical compounds, as well as their polymorphs, are studied in this work by Marcel, Hiyam and Andrew.

New paper in JACS

Our second in a series of collaborative projects with the research group of Steve Loeb.

In this work, Chris O’Keefe uses 2H SSNMR to probe the dynamics of crown ether rings, and how they change with phase transitions.
