The sample contains stars spanning a wide range of evolutionary phases, from G dwarfs to red clump stars. The abundances were derived from near-IR ({lambda}1.5-1.7{mu}m) high-resolution spectra (R=22500) from the SDSS-IV/Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey. A 1D local thermodynamic equilibrium abundance analysis was carried out using the APOGEE synthetic spectral libraries, via {chi}^2^ minimization of the synthetic and observed spectra with the qASPCAP code. We found significant abundance differences (~0.05-0.30dex) between the M67 member stars as a function of the stellar mass (or position on the Hertzsprung-Russell diagram), where the abundance patterns exhibit a general depletion (in [X/H]) in stars at the main-sequence turnoff. The amount of the depletion is different for different elements. We find that atomic diffusion models provide, in general, good agreement with the abundance trends for most chemical species, supporting recent studies indicating that measurable atomic diffusion operates in M67 stars.2019ApJ...874...97Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/874/97CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)I/329 : URAT1 Catalog (Zacharias+ 2015)III/284 : APOGEE-2 data from DR16 (Johnsson+, 2020)I/345 : Gaia DR2 (Gaia Collaboration, 2018)I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018)J/A+A/360/499 : Equivalent widths of 9 stars of M 67 (Tautvaisiene+, 2000)J/A+A/484/609 : BVI photometry and proper motions in M67 (Yadav+, 2008)J/A+A/490/777 : Abundances of Population II stars in NGC 6397 (Lind+, 2008)J/A+A/497/497 : Physical parameters from JHK flux (Gonzalez-Hernandez+, 2009)J/AJ/138/184 : RR Lyrae var. in 2 fields in M31 spheroid (Sarajedini+, 2009)J/A+A/508/833 : SACY III.
