摘要

In this article,we assign the Y(4390) and Y(4220) to be the vector molecular states D(D)1(2420) and D*(D)*0 (2400),respectively,and study their masses and pole residues in detail with the QCD sum rules.The present calculations only favor assigning the Y(4390) to be the D(D)1(1--) molecular state.
