The double Penning trap mass spectrometer JYFLTRAP has been employed to measure masses and excitation energies for 11/2− isomers in 121Cd, 123Cd, 125Cd, and 133Te, for 1/2− isomers in 129In and 131In, and for 7− isomers in 130Sn and 134Sb. These first direct mass measurements of the Cd and In isomers reveal deviations to the excitation energies based on results from β-decay experiments and yield new information on neutron- and proton-hole states close to 132Sn. A new excitation energy of 144(4) keV has been determined for 123Cdm. A good agreement with the precisely known excitation energies of 121Cdm, 130Snm, and 134Sbm has been found.
