Short summary
Magnetic resonance experiments are described using a mathematical object called the spin density operator. The article explores the regions of an abstract space called Liouville space which may be occupied by the density operator. The study is of particular relevance to hyperpolarized magnetic resonance, which is capable of generating greatly enhanced nuclear magnetic resonance signals which may be used, amongst other things, for imaging of metabolism in the human body.
