Abstract
Millimeter-wave direct absorption techniques were used to record the pure rotational spectrum of IZnCH$_{3}$ (X$^{1}$A$_{1}$). This species was produced by the reaction of zinc vapor with ICH$_{3}$ in the presence of a DC discharge. Rotational transitions ranging from J = 109 ${\rightarrow}$ 108 to J = 122 ${\rightarrow}$ 121 were recorded for I$^{64}$ZnCH$_{3}$ and I$^{66}$ZnCH$_{3}$ in the frequency range of 250${-290}$ GHz. The Ka = 0${-4}$ components were measured for each transition, with the K-ladder structure and nuclear spin statistics indicative of a symmetric top. As with HZnCH$_{3}$ (X$^{1}$A$_{1}$), the detection of IZnCH$_{3}$ provides further evidence for a zinc insertion process.
