Jet-cooled rotational spectrum of laser-ablated 1,3,5-trithiane (original) (raw)

The jet-cooled rotational spectra of the parent and three isotopic species (13 CC 2 H 6 S 3 , C 3 H 6 34 SS 2 and C 3 H 6 33 SS 2) in natural abundance of 1,3,5-trithiane have been observed by laser ablation combined with molecular-beam Fourier transform microwave spectroscopy. The r 0 and r s structures of the molecule have been determined from the rotational data. The sensitivity of the experimental setup proved to be high enough to observe the 33 S isotopomer in natural abundance. An analysis of the nuclear quadrupole hyper®ne structure due to the 33 S nucleus allowed the determination of the quadrupole coupling tensor, giving some insight about the electronic distribution around this atom.
