✦ Synopsis

From the analysis of the miaowave rotationa spectrum of IJdifluorocyclohexane in the frequency region 8-40 GHz the rotational constants (.4 = 3191.781, B = 1759.768, C= 1512.293 nlHzj, the centrifugal distortion coefficients @J= 124 X 104,DJ~--2.92 X 104, 0~ = -8.20 X 10d3) and the dipole moment and its components (p = 2556, iia = 2.415, pb = 0, fit = 0.837 debye) have been derived. Assuming that the CC and CH distances are the same as those of propane and that the ring structue in the chair form is symmetrical, the following structural palmeters are obtained: LCCC = 111.95", LFCF = 108.68", C-F = 1.356 A.

I ,2-&hiete has been produced by very-low-pressure pyrolysis of 1,3\_bithioIe-2-one. Its microwave spectrum has been observed and amed over the range X8-27 GIiz. All rotational constants and three centnfugal distortion constants have been adjusted in a least-squares fit from 12 rotational transition
