The microwave species of the $\mathrm{<mrow\; data-mjx-texclass="ORD">79</mrow>}Br$ and $\mathrm{<mrow\; data-mjx-texclass="ORD">81</mrow>}Br$ spectra of [ \begin{array}{ll} CH_{2} -CH_{2} - CH - CH_{2} Br & and\ CH_{2} -O- CH - CH_{2} Br & have \end{array} ] been studied in the 26.5 - 40 GHz region. The rotational conformations of the bromomethyl groups are compared with those of the fluorine and chlorine analogs.""
