The microwave spectrum of cis-1,2,3-trifluorocyclopropane a product from the ozonolysis of cis-1,2-difluoroethylene described in the preceding paper, has been investigated in the region B-40 GHz. A fit of the oblate symmetric top spectrum gives a rotational constant of 4064.93 $\pm$ 0.04 MHz, A molecular structure was determined using the rotational constants obtained from assignments of the monodeutero species, $CHFCHFC⏞DF$, and the carbon-13 species, $\mathrm{<mrow\; data-mjx-texclass="ORD">13</mrow>}CHFCHFC⏞HF$, The molecular parameters are $r(C-H)=1.095\pm 0.002A$, $r(C-C)=1.507\pm 0.002A$, $r(C-F)=1.354\pm 0.003A$, and $(HCF)=112.2\pm 0.2\circ$. A dipole moment of $3.89\pm 0-05$ D was determined from the second order Stark shifts of the J = 2-3 transition of the symmetric top species, $CHFCHFC⏞HF$.
