343/324 is a semitone-sized interval, defined as the difference between a stack of two 7/6 subminor thirds and a 9/7 supermajor third, making it a form of septimal diminished third. It is a gamelisma (1029/1024) above the Pythagorean minor second of 256/243, and is extremely close to 18/17, differing from it by the unnoticeable comma of 5832/5831.

Temperaments

Tempering out this comma equates a stack of three 7/6 subminor thirds with a 3/2 perfect fifth. While this is an unusual comma to temper out, being nearly 100 cents in size, it is tempered out in blackwood.
