Abstract
We examine relativistic effects in a coupled channel mixing calculation of corrections to charmonium energy levels. We find that the relativistic effect on the coupled channel mixing is large. Thus a relativistic treatment is necessary and may possibly lead to a larger admixture ofD andS states.
