A total of 245 previously unobserved millimeter- and submillimeter-wave transitions of (C-13)H{sub 3}OH for J not above 10 were assigned on the basis of measurements with a spectrometer which uses 40-60 GHz klystrons as fundamental radiation sources. These transitions were combined with the previously assigned 596 transitions and were analyzed using a modified internal-axis-method model which treats the symmetric (A) and degenerate (E) substates separately. As a result of the expansion of the (C-13)H{sub 3}OH data set to cover the same range as the data set of a previous (C-12)H{sub 3}OH analysis by Anderson et al. (1990), rigid criteria of self-consistency could be applied for the selection and the value of the constants between the isotopic species. The spectral constants obtained were used to make accurate predictions of 562 additional transitions of (C-13)H3OH for v(t) = 0, 1, 2 and rotational quantum number J equal to or less than 12. 18 refs.
