The nuclear molecular resonances observed in α+12C and α+16O systems are described in a diatomic-like molecular picture using a Morse-type bonding potential. The depths of the bonding potentials are found to be 11.5 MeV and 11 MeV respectively, with long range of about 15 fm. Both the bound and resonance states of these potentials are calculated which compare quite well with the observed states. The diatomic-like rotational and vibrational picture of the quasi-molecular states proposed earlier for12C+12C system system is found to be quite valid for α+12C and α+16O systems. In these two systems, the rotational vibrational characteristics are equally well pronounced as in the12C+12C system.
