Observations of the 2(0) to 3(-1) E-type transition of C-/sup 13/H/sub 3/OH at 14.78 GHz have been made toward the continuum sources Sgr A, Sgr B2, and W33. For the cases of Sgr B2 and one position in Sgr A, a C-12/C-13 abundance ratio of 40 is obtained which is much higher than the values (20-25) found for other molecules. For W33, the value 50 obtained (50) is lower than that derived from H/sub 2/CO observations, but is comparable to that noted from CO observations. 10 refs.
