Astrophys.// **499**, (2009) 215–232.\\ These are the second and third molecules after [[http://www.astro.uni-koeln.de/site/vorhersagen/molecules/ism/AAN.html|aminoacetonitrile]] to be detected newly within this molecular line survey.\\ Ethyl formate is the second formate to be detected in the ISM after [[http://www.astro.uni-koeln.de/site/vorhersagen/molecules/ism/Methylformiat.html|methyl formate]]. The parent species formic acid, [[http://www.astro.uni-koeln.de/site/vorhersagen/molecules/ism/Formic_Acid.html|HCOOH]], has also been detected. The isomeric methyl acetate, CH<sub>3</sub>OC(O)CH<sub>3</sub>, has not yet been detected – in part because of very limited laboratory data.\\ //n//-Propyl cyanide is the third member after methyl cyanide, CH<sub>3</sub>CN, and ethyl cyanide, [[http://www.astro.uni-koeln.de/site/vorhersagen/molecules/ism/EtCN.html|C<sub>2</sub>H<sub>5</sub>CN]]. ---- Contributor(s): H.
