The experiment SPIRALES coupling a tunable infrared laser to a pulsed supersonic free jet has allowed us to reinvestigate the high-resolution absorption spectroscopy of the SF 6 dimer in the ν3 mode region under various experimental conditions. In addition to the SF 6 dimer spectrum so far reported, we demonstrate the existence of two new spectral features: i) one assigned to a second conformer of this species, characterized by a larger interatomic distance as well as ii) a complex (SF 6) 2-He.
