Review of BESIII results

Recent results of the BESIII experiment in spectroscopy of spin-singlet charmonium are presented. Properties of hc, ηc and ηc′ states are measured using the largest data sample of 106M of ψ′ decays. The masses, widths, and production rates of these states are reported. The transitions between charmonium state ψ′ → γγJ/ψ and the measurement of multipole amplitude in ψ′→γχc2 are presented. The branching fractions for ηc′,χcJ decays to vector meson pairs and the radiative decay χcJ→γγ are reported. Some preliminary results of charm meson decays are presented.
