High resolution FTIR spectra of the {nu}{sub 2}/{nu}{sub 4} and the {nu}{sub 1}/{nu}{sub 3} bands of {sup 120}SnD{sub 4} have been measured with a Bruker 120 HR interferometer. The sample was prepared under vacuum using a two step synthesis. The {nu}{sub 2}/{nu}{sub 4} region (425-620 cm{sup -1}) was studied using a liquid He-cooled bolometer, while an MCT detector was used in the {nu}{sub 1}/{nu}{sub 3} region (1275-1455 cm{sup -1}). The resolutions of the spectra are 0.0033 cm{sup -1} and 0.0024 cm{sup -1}, respectively. The {nu}{sub 1}/{nu}{sub 3} band system has been analyzed rotationally, and a set of molecular parameters have been obtained The measurement of the first and second stretching overtones is in progress, too. The results will be compared with those of normal stannane, SnH{sub 4}. In the case of normal stannane, vibrational localization has been found to take place in stretching vibrational overtones. Thus the dynamical symmetry of stannane, a spherical top molecule, has been found to become that of a prolate symmetric top.
