The hydrogen‐bonding networks of the naturally occurring polyol d ‐ribitol have been revealed in a supersonic expansion by laser ablation and broadband Fourier transform microwave spectroscopy. Sequential O−H⋅⋅⋅O hydrogen bonds in a clockwise or counter‐clockwise arrangement stabilize five conformations of ribitol, wrapping round the carbon backbone. Hydrogen‐bond contacts that stabilize extended conformers have been related to the active role of the ribityl chain in flavoprotein mechanisms.
