Conjuration vs Evocation.
Also, you can take Weapon Focus (et al.) for rays, but not ranged touch attacks in general. Not a huge selling point as I've never seen anyone do that, but it's an option.
The people who do it are ray sorcerers and sorcerer/rogue/arcane tricksters. Both combos can use the extra +1 to hit, even going after touch AC since they aren't full BAB, and both make extensive use of rays.
