Abstract
Several exclusive charmonium decays are considered in the parton quark perturbative QCD framework. Many of these decays are forbidden by the helicity conservation of massless quarks which couple to gluons; however, they are experimentally observed. After reviewing some of these cases, possible non perturbative corrections or alternative decay mechanisms are considered and discussed; the role of spin data in discriminating between different models can, once more, be crucial.
