Narrative: Aircraft X departing Santa Monica; (SMO) airport on departure climbing to 3;000 feet expected to intercept an LAX radial and turn westbound. Departure was not in communications with Aircraft X and was unable to turn the pilot. Attempted to contact SMO and request communications and a turn of the aircraft. Simultaneously Aircraft Y was departing LAX south complex RWY 25 climbing to 5;000 feet. The two targets were converging so I turned Aircraft Y southwest bound into Manhattan Radar (6S) sky and completed a point out and stopped Aircraft Y beneath traffic being worked by Manhattan. Once I gained communications with Aircraft X I turned him IMMEDIATELY to a heading of 265; [and] then followed up shortly with the Brasher statement advising the pilot of a possible pilot deviation.LAX south complex departures should remain stopped until SMO traffic has turned westbound then LAX Tower should be able to resume departures.


Second narrative: While departing from SMO and executing the SMO noise abatement procedure for a Beechcraft 400XP. The clearance was to fly runway heading and cross LAX 310 radial; then turn right heading 265 degrees while climbing to 3;000 feet MSL. On the initial climb; less then 1;000 feet MSL and on SMO Tower frequency; the SMO Tower called 'VFR traffic helicopter; 12 o'clock' followed by a 'traffic Alert'; on TCAS; which was the 'TA'. I; the PIC and non pilot flying; was trying to spot the traffic on my side (right); while the pilot flying was completing the low noise/low power (noise abatement) procedures and increasing climb due to traffic avoidance. The SMO Tower then handed us off to Departure (on 125.2) where we checked in with no delay 'climbing to 3;000 feet; runway heading' (realizing we had inadvertently passed the 310 radial while avoiding traffic). At this time we had just finished cleaning up the aircraft (flaps 0 and power increased). Departure then directed us to 'turn 265 heading immediately' and we complied.All these facts listed above happened in the initial climb phase while low to the ground and in high VFR / IFR volume airspace. This being said; the crew was in a high work load environment at the time of the situation.


Synopsis: SCT Departure Controller and SMO departing pilot describe situation where the departure didn't turn when expected and became a conflict for a departure off of LAX.
