Atmospheric composition provides essential markers of the most fundamental properties of giant exoplanets, such as their formation mechanism or internal structure. New-generation exoplanet imagers, like VLT/SPHERE or Gemini/GPI, have been designed to achieve very high contrast (< 15 mag) at small angular separations (<0.500) for the detection of young giant planets in the near-infrared, but they only provide very low spectral resolutions (R < 100) for their characterization. High-dispersion…
