How do we study molecules that are too small to see? This episode dives into the high-tech world of spectroscopy—the ultimate detective toolkit for chemists. We uncover how scientists use infrared light, nuclear magnetism, and mass spectrometry to identify unknown substances, catch drug cheats, and even analyze ancient artifacts.

How do forensic scientists track poison in crime investigations? What can chemistry reveal about lost civilizations? And how do we know what’s inside distant planets without ever going there?

Get ready for a mind-blowing look at how we “see” the invisible world of molecules—using light, magnets, and a little bit of science magic.
