We search for molecular tracers of high-energy irradiation by the protostar in the hot inner envelope. The Submillimeter Array (SMA) has observed the high-mass star forming region AFGL 2591 in lines of CS, SO, HCN, HCN(nu2=1), and HC^15^N with 0.6" resolution at 350GHz probing radial scales of 600-3500AU for an assumed distance of 1kpc. The SMA observations are compared with the predictions of a chemical model fitted to previous single-dish observations.2007A&A...475..549Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/475/549CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/475/549https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/475/549http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/475/549https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/475/549https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/475/549http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/475/549GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapRadiodefaultJ/A+A/475/549/table1Observed molecules and properties in the area defined by the SMA synthesized beam centered on the maximum position of the maprecnoRecord number assigned by the VizieR team.
