The ~(1440) seems to be split into two components, an 7/(1410) and an r/(1470). The splitting might signal a node in the 7/(1440) wave function suggesting that the 7/(1440) is a radial excitation. The partial width of the ~/(1440) for the P7 decay leaves a little room for an exotic interpretation of

We review several aspects of the phenomenology of P-wave ~Q mesons: mass splittings, effective strong couplings and leptonic constants. We also describe a QCD sum rule determination to order c~s of the form factor T1/2(y) governing the semileptonic B decays to the charm doublet with jR = (0 + 1 + ',
