Magnetic resonance is often presented as the prime example of the value of fundamental research. Indeed, the physicists who measured nuclear gyromagnetic ratios and spin quantum numbers 80 years ago could never have dreamed of its profound impact on chemistry, materials science, and medicine. But by the early 1960s, most physics departments (and many chemistry departments) viewed the fundamental questions as solved. That perspective is simply wrong, as demonstrated amply by Alex Pines and many of the people who came from his laboratory. In this talk, I will highlight some of the ways the modern picture has changed (multiple-quantum coherences between spins separated by millimeters; dipolar effects in solution; symmetry-forbidden, protected spin states with ultraslow relaxation). I will then focus on what I believe is a disruptive technology for the future of magnetic resonance: cheap, easy, general and fast methods which combine organometallic chemistry and quantum physics to enhance molecular magnetization by 104-105, with implications for both portable MRI and improved chemical analysis.
