cds-question@unistra.fratomic-physicsradio-astronomystellar-atmospheric-opacityWe build an accurate database of 5200 HCN and HNC rotation-vibration energy levels, determined from existing laboratory data. 20000 energy levels in the Harris et al., 2002ApJ...578..657H (HPT), linelist are assigned approximate quantum numbers. These assignments, lab determined energy levels and HPT energy levels are incorporated in to a new energy level list. A new linelist is presented, in which frequencies are computed using the available lab determined energy levels, and the HPT ab initio energy levels otherwise.2006MNRAS.367..400Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/VI/121CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/119 : High accuracy computed water line list - BT2 (Barber+, 2006)VI/131 : Linelist of H13CN/HN13C (Harris+ 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VI/121https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VI/121http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VI/121https://vizier.cds.unistra.fr/viz-bin/votable?-source=VI/121https://vizier.iucaa.in/viz-bin/votable?-source=VI/121http://vizieridia.saao.ac.za/viz-bin/votable?-source=VI/121GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapRadiodefaultVI/121/enlvsEnergy level list of HCN/HNCP[0,1] Parity of the lower statephys.atmol.parityintIndex[1,168110] Unique index number of statemeta.idintprimaryindexedJ[0,60] Rotational quantum number of lower statephys.atmol.qnintn[1,2220] Number of lower states in J-parity blockmeta.idintEaiab initio energy of the statecm**-1phys.energy;phys.atmol.leveldoubleiso[-2,1] Isomer configuration of state 0=HCN, 1=HNCphys.atmol.configurationintv1[-2,3] H-(CN) stretch approximate quantum numberphys.atmol.qnintv2[-2,14] Bend approximate quantum number of statephys.atmol.qnintl[-2,13] Vibrational angular momentum approximate quantum number of statephys.atmol.qnintv3[-2,4] C-N stretch approximate quantum numberphys.atmol.qnintElab?
