Narrative:
I cleared a BE36 for takeoff [runway] 33L; then later a MD88 off [runway] 27. The 27 departure turned to 235 heading per the SID and I had anticipated the turn and assigned the BE36 a 290 heading; eventually this aircraft needed to go south behind the MD88. I had both aircraft in sight; the MD88 was ahead of the BE36 and I turned the BE36 to a 210 heading. This aircraft was climbing to 3;000 ft and the MD88 was out of 3;000 ft and ahead of the BE36's projected track. The pilot of the BE36 later claimed that I 'took (him) right through the wake turbulence of that aircraft.' maybe I could have issued the traffic to the BE36 but it was not needed in my opinion.
