A special iridium compound can make NMR signals much stronger for certain molecules like pyridine by using hydrogen gas, making it easier to detect these molecules in scientific tests.
The iridium compound loses a pyridine molecule to form a simpler structure that helps transfer polarization during the SABRE process.
The iridium compound has parts that move around quickly at room temperature, with pyridine molecules leaving at about 8 times per second and hydrogen atoms swapping positions about 3.6 times per second.
When this iridium compound is used with special hydrogen gas, it can make NMR signals for pyridine much stronger—over 200 times stronger in some cases.
Over time, the iridium compound changes into a different structure that can swap hydrogen atoms in molecules, which is useful for making labeled compounds for medical imaging.
