Narrative:

We were cleared to descend from 16;000 to 11;000 ft. While descending through 15;000 ft I pulled the power levers back for the descent. At that time the right engine ignition light illuminated; followed by loud popping noises; a rapid rise in itt through 965 degrees C was observed and the right engine over temp light illuminated. I immediately shut down the right engine; had the first officer declare an emergency; and requested to land at ZZZ which was our nearest suitable airport. I then requested and complied with the engine shutdown QRH for the right engine.while being vectored for the approach we ran the descent; approach; and before landing checklists. A normal landing was performed followed by a normal taxi to the ramp; we were marshaled to a parking spot and shutdown the aircraft. Upon parking we were met by emergency; ramp and station personnel. While I was communicating with operations; all passengers disembarked the aircraft normally and were assisted by the on duty station manager. No passengers or crew were injured as a result of this event.
