โœฆ Synopsis


Rotational transitions for the S02-H2S complex were given in the above paper. It now appears that the 101+2,-,2, 202+303 and 2,, + 3 Lz transitions are not split by inversion or hindered-rotation interactions as originally believed. Two components with splittings of 21.6, 20.4 and 22.7 MHz were observed in the same frequency region expected for each of these transitions. One of the "extra" transitions is now assigned to a c-dipole transition, one to an a-dipole transition and two to another molecular species. A total of 24 transitions are now assigned for SO*-H2S, and the confidence in the present assignments is substantially increased. The preliminary assignments are basically correct except for the pairs of lines with z 20 MHz splittings, and two of these lines were correct. The assignments allow determination of all three rotational constants and a refinement of the structure of the complex. The previous structure with two hydrogen bonds is supported by the new data and assignments with a present O...H distance of 2.81 A. The present S...S distance of 3.61 8, indicates the possibility of a sulfur-sulfur interaction in addition to the two hydrogen bonds. Work is continuing on isotopically substituted species and details will be published [ I],
