2L 1s⟨3/2⟩ is a 3/2-equivalent (fifth-equivalent) moment of symmetry scale containing 2 large steps and 1 small step, repeating every interval of 3/2 (702.0¢). Generators that produce this scale range from 234¢ to 351¢, or from 351¢ to 468¢. Scales of this form are always proper because there is only one small step.
