 Title: THz spectroscopy of excited torsional states of monodeuterated methyl formate (DCOOCH3) Author(s): Carvajal, Miguel Contributor(s): Kleiner, Isabelle; Drouin, Brian; Pearson, John; Yu, Shanshan; Duan, Chuanxi Subject(s): Spectroscopy of Large Amplitude Motions Abstract: Recently, a measurement of the rotational spectrum of \chem{DCOOCH_3} has been carried out in the frequency range from 0.85 to 1.5 THz at Jet Propulsion Laboratory (JPL) (Duan et al. 2015). These JPL data and the available spectroscopic millimeter- and submillimeter-wave data (Margulès et al. 2010 and references therein) of the ground state were analyzed using the Rho Axis Method (RAM) (Kleiner 2010). At present, a new analysis of JPL lines of \chem{DCOOCH_3} in the first excited v$_{t}$=1 torsional states is undertaken. This analysis may help the future identification of v$_{t}$=1 lines in the interstellar and circumstellar media as was carried out for the v$_{t}$=0 lines in Orion KL (Margulès et al. 2010). In this communication, the progress of this study is presented as well as a short outline of the spectral analyses accomplished for other methyl formate isotopologues. \footnote{This research is supported by the FIS2014-53448-C2-2-P project (MINECO, Spain), the French PCMI (Programme National de Physique Chimie du Milieu Interstellaire), and the National Natural Science Foundation of China (Grant No. 11174098).
