How do they know it's nonradiative? lysdexia 02:55, 28 Oct 2004 (UTC)

I'm not sure that I understand your question. If you look at the object, you don't see any light coming out but the energy level changes so you know it lost energy. Since you didn't see any light, it must have lost the energy in a non-radiative (that is not causing ratiation or light) way.
