Description
In this talk, we will present the results on the charmonium
spin singlet states below the open charm threshold, including
$h_c$, $\eta_c$, and $\eta_c(2S)$. The masses, widthes, and
production rates of these states will be reported. The results
are based on a data sample of 106 million $\psi^\prime$ events
collected with the BESIII experiments at the BEPCII collider.
