Abstract

Over 30 lines of the ground states inversion-rotation spectrum of trimethylene sulfide monomer have been measured to 5 kHz resolution in a Balle-Flygare pulsed nozzle, molecular beam Fourier transform microwave spectrometer. A Hamiltonian with Coriolis coupling, inversion splitting, rotational constants and centrifugal distortion constants for each inversion level will be discussed. The hyperfine spectrum due to the methylene hydrogens has also been observed. The use of the perturbations of the ring-puckering potential to study Van der Waals bonding will be discussed
