We consider finite time blow up solutions to the critical nonlinear Schrödinger equation http://static-content.springer.com/image/art%3A10.1007%2Fs00220-004-1198-0/MediaObjects/s00220-004-1198-0flb1.gif For a suitable class of initial data in the energy space H 1, we prove that the solution splits in two parts: the first part corresponds to the singular part and accumulates a quantized amount of L 2 mass at the blow up point, the second part corresponds to the regular part and has a strong L 2 limit at blow up time.
