Narrative:
I was working R2. There was another controller working D2. He told me that there were two planes that would be departing lih. Aircraft X departed and I told him radar contact. Then; aircraft Y departed; and I radared them as well. I noticed that the heading that aircraft Y was on seemed kind of close behind the aircraft X; but I assumed that he was still making the turn. I watched it for a little bit more and realized that aircraft Y was not turning any further away from aircraft X. I looked over at the strips and saw that the D side had departed aircraft X on a 030 heading and aircraft Y on a 065 heading. There was only 35 degrees divergence instead of the required 45 degrees. The D side needs to be more careful. I will try my best to double check the D side's work.
