Abstract:The pure rotational spectrum of ZnBr ($^{2}$$\Sigma$$^{+}$) has been recorded using millimeter-wave direct absorption spectroscopy. This species was generated in the gas phase via the reaction of zinc vapor with CH$_{3}$Br in the presence of a DC discharge. Multiple rotational transitions were measured for 6 isotopologues ($^{64}$Zn$^{79}$Br, $^{64}$Zn$^{81}$Br, $^{66}$Zn$^{79}$Br, $^{66}$Zn$^{81}$Br, $^{68}$Zn$^{79}$Br, and $^{68}$Zn$^{81}$Br) in the frequency range of 270-300 GHz, each of which consisted of spin-rotation splittings. Furthermore, transitions originating in the v = 1 through 3 excited vibrational states for certain isotopologues were obtained. The equilibrium rotational constant for $^{64}$Zn$^{79}$Br (\textit{B$_{e}$}) was calculated to be near 2780 MHz, resulting in an equilibrium bond length (\textit{r$_{e}$}) of 2.25 \AA.
