A1 Tercero, Belen A1 Cernicharo, José A1 Alonso Hernández, José Luis AB The millimeter wave spectrum of acrylic acid (CH2=CH–COOH), the simplest unsaturatedcarboxylic acid, was measured and analyzed from 130 to 360 GHz. Additional measurementsfrom 18 to 26.5 GHz were also made using a waveguide CP-FTMW spectrometer. More than4000 rotational lines were assigned to s-cis- and s-trans-acrylic acid in their groundvibrational states. New laboratory data of acrylic acid were then used to search for its spectralfeatures in Orion KL, Sgr B2, and W51 molecular clouds. An upper limit to the columndensity of acrylic acid in Orion KL is provided.
