✦ Synopsis

The free jet absorption millimeter-wave spectrum of methylthioglycolate-SD has been investigated in the 60-78 GHz frequency range. The double-minimum potential associated with the SD group torsion generates a vibrational spacing D 01 Å 8285(5) MHz between the O / and O 0 states of the A sublevel. This splitting, compared to the corresponding value of 18 953 MHz for the normal species, suggests a large involvement of the sulfur atom in the motion. A model is given to describe this motion.
