We perform infrared studies of the Landau level (LL) transitions in monolayer graphene in magnetic fields up to B = 18T. We observe both intra‐band transitions between neighboring hole/electron LLs, as well as inter‐band transitions between hole and electron LLs, all proportional to √B in energy. The lack of precise scaling between different LL transitions and the unexpectedly large energy shifts as a function of the LL filling factor near the charge neutrality point suggest considerable contributions of many‐body effects to the infrared transition energies.
