cds-question@unistra.frcometsradio-astronomyradio-spectroscopyA spectral survey in the 1mm wavelength range was undertaken in the long-period comets C/2012 F6 (Lemmon) and C/2013 R1 (Lovejoy) using the 30m telescope of the Institut de radioastronomie millimetrique (IRAM) in April and November-December 2013. We report the detection of ethylene glycol (CH_2OH)_2 (aGg' conformer) and formamide (NH_2CHO) in the two comets. The abundances relative to water of ethylene glycol and formamide are 0.2-0.3% and 0.02% in the two comets, similar to the values measured in comet C/1995 O1 (Hale-Bopp). We also report the detection of HCOOH and CH_3_CHO in comet C/2013 R1 (Lovejoy), and a search for other complex species (methyl formate, glycolaldehyde).2014A&A...566L...5Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/566/L5CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/564/L2 : CH3OH line parameters in comets ISON & Lovejoy (Agundez+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/566/L5https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/566/L5http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/566/L5https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/566/L5https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/566/L5http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/566/L5GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapRadiodefaultJ/A+A/566/L5/listList of FITS spectraNameComet namemeta.id;meta.maincharNxNumber of channelsmeta.numberintrecnoRecord number assigned by the VizieR team.
