Molecular Structure and Conformation of Dimethyltrisulfane, CH3SSSCH3, As Determined by ab Initio Molecular Orbital Calculations and Gas-Phase Electron Diffraction

A sample of dimethyltrisulfane (98%) was obtained from Eastman Kodak Co. and was used without further purification. The diffraction data were collected using the Oregon State University apparatus at a nozzle-tip temperature of 383 K, using Kodak lantern slide photographic plates. Camera heights of 747.6 and 299.15 mm, respectively, for the long and middle camera experiments were used. Four photographic plates from each of the two camera distance experiments were selected for structural analyses. The usual data reduction procedures were followed. The intensity data were averaged and interpolated at integral q units (q ) 40 I -1
