The 115Sn, 117Sn and 119Sn nuclear spin-rotation constants in stannous monoxide, SnO, and a new multi-isotopomer analysis

A Fourier transform microwave spectrometer has been used to make high resolution measurements on the J = 1–0 rotational transition for 11 isotopomers of SnO. For the most abundant isotopomer the transition was observed in the v = 0, 1, 2, and 3 states. Magnetic hyperfine structure was observed in th...

Description
Summary:A Fourier transform microwave spectrometer has been used to make high resolution measurements on the J = 1–0 rotational transition for 11 isotopomers of SnO. For the most abundant isotopomer the transition was observed in the v = 0, 1, 2, and 3 states. Magnetic hyperfine structure was observed in the transitions for 115Sn 16O, 117Sn 16O and 119Sn 16O. The nuclear spin-rotation constant C I (Sn) has been determined for these isotopomers for the first time and these constants have been related to nmr shielding parameters. A multi-isotopomer analysis, including data from the 120Sn 17O and 120Sn 18O isotopomers, has been performed on the data. Born–Oppenheimer breakdown parameters were required in the fit and these parameters have been compared to those for the other Sn-chalcogenides.
