Abstract:The detection of propenal (acrolein) in Sgr B2 is based in two transitions detected with the Green-Bank Telescope,\footnote{J.~M.~Hollis, P.~R.~Jewell, F.~J.~Lovas, A.~Remijan, H.~M$\o$llendal \textit{Astrophys. J.} \textbf{610},\textit{ L21-L24}, (2010)} operating in the frequency range 18-26~GHz. A combination of Stark modulated microwave spectroscopy and frequency modulated millimeter- and submillimeter-wave spectroscopy has been used to record the rotational spectrum of propenal from 26~to~675~GHz in order to provide accurate rotational parameters for the identification of new lines of propenal in the interstellar medium. Ground state and the vibrational excited states below 700~cm$^{-1}$ of trans-propenal ($\nu$$_{18}$, 2$\nu$$_{18}$, $\nu$$_{13}$, 3$\nu$$_{18}$, $\nu$$_{18}$+$\nu$$_{13}$, $\nu$$_{12}$, $\nu$$_{17}$, 4$\nu$$_{18}$, 2$\nu$$_{18}$+$\nu$$_{13}$, 2$\nu$$_{13}$) have been analyzed in a global fit taking in to account Coriolis and Fermi interactions. Spectroscopic constants for all three $^{13}$C trans-isotopologes in natural abundance as well as ground state spectroscopic constants for cis-propenal are also reported.
