Abstract
Fourier Transform far infrared spectra of unstable stannyl chloride, bromide and iodide have been measured in the gas phase with a resolution of 0.04 cm-1. At pressures below 10 mbar, their lifetimes at 0 °C in preconditioned cells were found to be 10-30 min. The v3 fundamentals and hot bands of the series (n + 1)v3 - nv3 have been observed. Rotational J structure has been resolved for monoisotopic samples, and band origins v30, anharmonicity constants x33, ɑ3B and DJ0 values have been determined from the rovibrational analyses. The following v30 values were obtained: H3116Sn35Cl 375.470 (5), H3116Sn37Cl 367.689 (6), H3116Sn79Br 263.566 (5) and H3116SnI 209.759 (6) cm-1.
