Narrative:

Aircraft X was climbing off of ifp on the IFR departure to 8000 feet. While in the turn and climbing on the departure; aircraft X turned and climbed into a VFR overflying westbound over ifp. I was not talking to the VFR aircraft and not yet in contact with aircraft X when aircraft X turned and climbed into the VFR aircraft. I tried giving a full route clearance away from the target; unfortunately aircraft X did not get it in time. When I checked to see if they were in fact on frequency; they advised me that they responded to a RA. I took down information and continued to give them the correct clearance. Not sure if this could have been avoided at all since I was not in communication with the other aircraft and I don't think ifp tower could have given them traffic in time.I'm not sure how to avoid this situation since I was not in contact with the VFR target. No way to know 100% what altitude to issue when not verified.

Title: ARTCC Controller reported an aircraft departing a controlled airport on an IFR clearance responded to an RA for a VFR aircraft. The IFR aircraft had not yet contacted the Controller and the VFR aircraft was not in communication with ARTCC.
