Two different conformers (axial (in the left picture) and equatorial (right)) are formed in a supersonic jet stream when trimethylene sulfide, a floppy molecule with a large‐amplitude ring‐puckering motion, is complexed to hydrogen chloride. The axial conformer is the most stable. The relaxation from the equatorial to the axial conformational has been observed using different carrier gases.
