We study the properties of charmonium states at finite temperature inquenched QCD on large and fine isotropic lattices. We perform a detailedanalysis of charmonium correlation and spectral functions both below and above$T_c$. Our analysis suggests that both S wave states ($J/\psi$ and $\eta_c$)and P wave states ($\chi_{c0}$ and $\chi_{c1}$) disappear already at about $1.5T_c$. The charm diffusion coefficient is estimated through the Kubo formula andfound to be compatible with zero below $T_c$ and approximately $1/\pi T$ at$1.5 T_c\lesssim T\lesssim 3 T_c$.
