Abstract

An extensive search has been conducted to confirm transitions of \textit{trans}-ethyl methyl ether (tEME), (C$_2$H$_5$OCH$_3$), toward the high mass star forming region W51 e1/e2 using the 12 m Telescope of the Arizona Radio Observatory (ARO) at 2 mm and 3 mm wavelengths. Typical peak to peak noise levels for the present observations of W51e1/e2 were between 10 mK to 30 mK, indicating an upper limit of the tEME column density of $\leq$ 1.5 $\times$ 10$^{15}$ cm$^{-2}$, this would make tEME at least a factor 2 times less abundant than dimethyl ether (CH$_3$OCH$_3$) toward W51 e1/e2. We have also performed an extensive search for this species toward the high mass star forming region Sgr B2(N-LMH) with the NRAO 100 m Green Bank Telescope (GBT). No transitions of tEME were detected and we were able to set an upper limit to the tEME column density of $\leq$ 4 $\times$ 10$^{14}$ cm$^{-2}$ toward Sgr B2(N-LMH). We will discuss these observations in the context of detecting large complex organic species toward star forming regions with next generation telescopes such as ALMA.
