The elements of interest present lines in different wavelength regions, and some of them show lines only in part of the spectra. In the present work, the CNO trio, the a-elements Mg, Si, Ca, and Ti, and odd-Z Na and Al are examined as measured from optical and H-band lines. The aim of this work is to carry out a detailed comparison of stellar parameters and abundances derived in the optical and near-infrared (H-band). We also inspect the best available lines for a list of bulge stars previously analyzed by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) team in the H-band and by our group in the optical. This work is mainly of interest to spectroscopists. In the present work, we compared the stellar parameters and abundance results derived from APOGEE H-band spectra with optical analyses based on Ultraviolet and Visual Echelle Spectrograph at the Very Large Telescope (VLT/UVES) data for eight bulge stars. We point out the most suitable wavelength region for each of the studied elements, and highlight difficulties in the derivation of stellar parameters both in the optical and H-band. The near-infrared will allow observations of a large number of stars in the near future given new instruments soon to be available. The identification of spectral lines in this spectral region and the investigation of their reliability are ongoing efforts worldwide. New instruments will also allow simultaneous observation of H-band and optical.2024A&A...687A..66Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/687/A66CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/687/A66https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/687/A66http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/687/A66https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/687/A66https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/687/A66http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/687/A66GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/687/A66/table2 (stars: Identifications from internal name, Gaia, 2MASS and OGLE numbers)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/687/A66/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/687/A66/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/687/A66/table2?GETtext/xml+votable180.050000true262.77438333-29.976527780.0055555555555555560/1.143914381504295e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/687/A66?format=asciiUVOpticalInfrareddefaultJ/A+A/687/A66/table2stars: Identifications from internal name, Gaia, 2MASS and OGLE numbers2MASS2MASS name (2MHHMMSSss+DDMMSSs)meta.idcharOGLE?
