There are now five established $X$ particles named as $X(3872)$, $X(3900)$, $X(4260)$, $X(4360)$, and $X(4660)$. Since the first $X$ particle $X(3872)$ was discovered during the search for the remaining P charmonium states, it is valuable to check whether the established $X$ particles can be explained by quarkonium model. In this paper, we try to calculate the mass spectra of charmonium system by considering spin-dependent forces deduced from one gluon exchange diagrams.
