dc.description.abstract The microwave spectra of (Z) Propanethial S-Oxide (ethyl sulfine) isotopomers, $C_{2}H_{5}CHSO$ AND $C_{2}H_{5}CH^{34}SO$, were assigned using pulsed beam FT microwave spectroscopy, Ethyl sulfine, the species responsible for onion tears, has been generated via an on-line pyrolysis in which the precursor, 2-metyl-2-propyl vinyl sulfoxide, was flowed through a furnace coupled directly to the pulsed nozzle. Rotational constants (in MHz) obtained from a fit of {a-} and {b}-type transitions to a Watson Hamiltonian are A=10182.258(3), B=2209.567(1), C=1997.111(1) for the normal species, and A=10113.393(2), B=2181.858(1), and C=1972.327(1) for the sulfur-34 isotope. The isotopic moments of inertia are consistent with a planar C-C-S-O framework in which the oxygen and the ethyl group are syn to each other with respect to the C-S bond. [FIGURE]. en_US
