The J=0→1, K=0→0 rotational lines of methyl alcohol have been observed and identified with the Stark effect for C12H3O16H, C13H3O16H, C12H3O16D, C13H3O16D, C12D3O16H, and C12D3O16D. These lines are obtained not only for the molecules in the ground state but also for those in the first two torsional excited states, n=1 and n=2. All these lines except those of the C12D3O16D were observed to be doublets, the doublet separation being different for different molecules. Some further experimental data on C12D3O16H, C12H3O16D, and C13H3O16H are included in this paper.
