One example is the photoelectric effect.
All the photon's energy is 'used up' knocking out an electron and giving the electron kinetic energy.

A familiar example is when microwaves are used in cooking food. The microwave radiation is absorbed by water molecules and converted to kinetic energy causing the water molecules to spin. Within a very short period of time, those spinning water molecules agitate other molecules and the entire process results in heat. A photon gets absorbed but heat energy is the result.

have a look at inelastic photon scattering and see if this is what you are looking for :
