What is it about?

Aliphatic chains are one of the most frequent molecular building blocks in biochemistry. Here we present a novel type of spectroscopy to study the structure and dynamics of these chains using a sophisticated quantum process that can be explained in terms of spin order propagation.

Why is it important?

For over a century, spin waves have been fundamental in understanding ferromagnetism, conductors, and semiconductors. Here we discover that spin waves can be excited in molecular aliphatic chains with liquid-state nuclear magnetic resonance. These experiments hold promise for advancing research in bio-molecular dynamics and drug discovery.


Working on this project was very exciting as the initial observations were a consequence of a lucky mistake. Then gradually we realized that these phenomena can be understood in a much wider context and there is beautiful underlying physics. This is a truly interdisciplinary project where quantum physics meets spectroscopy and puts those in good use for chemical and biological applications.
