Abstract
The previous $work^{1}$ on the ultraviolet and infrared spectra of so-called sulfur monoxide has been interpreted on the basis of a molecule with the formula of $S_{2}O_{2}$. An examination of the microwave spectrum shows conclusively that the major component of so-called sulfur monoxide is in reality disulfur monoxide, $S_{2}O$. The low J valued microwave transitions of $S_{2} O$ consist of R branch lines (a-dipole) and Q branch lines (b-dipole). The values of B-C obtained from the a-dipole and b-dipole lines agree within experimental error. The rotational constants for the $S_{2}^{32, 32}O^{16}$ species are $A - 41,914.3; B = 5,059.1; C = 4,507.0$ mc/s. These data are consistent with an $S-S-O$ structure and angle of about $120^{\circ}$. A new interpretation will be given of the ultraviolet and infrared spectra of $S_{2}O$.
