Final answer:
Internal conversion is a type of isomeric transition where the excited nucleus transfers energy directly to an inner electron, causing its ejection.
Step-by-step explanation:
The relationship between isomeric transition and internal conversion involves the process of energy release from an excited nucleus. Isomeric transition is a type of radioactive decay where the nucleus of an isomer goes from a higher to a lower energy state by emitting a gamma ray or through internal conversion. Internal conversion, on the other hand, is a process where the excited nucleus transfers its energy directly to an electron in one of the lower atomic orbitals, causing that electron to be ejected from the atom. Internal conversion is thus a type of isomeric transition.
