The Raman spectra of the vapors of several deuterated analogs of trimethylene sulfide in the ring puckering region are reported. Several puckering energy level separations unavailable from the far‐infrared spectra are deduced and compared to values calculated with a quadratic‐quartic potential function. The “best fittingo” potential constants and hence the inversion barriers computed with the new data are virtually the same as those reported previously. For the perdeutero compound one far‐infrared assignment was corrected to fit the Raman data and new values for the potential constants and the barrier were calculated.
