The In nuclei have been populated as fission fragments in reactions induced by heavy ions. Level schemes have been built from 
-rays detected using the Gammasphere array. Medium-spin states of 
In
nuclei have been identified for the first time, while the level schemes of 
In
were enriched. The observed states at lower excitations and at medium spin can be described by the coupling of the proton g
hole to the neutron or neutron-hole in the h
orbital. This coupling can now be followed in all odd-odd In isotopes from 
In
to 
In
.
