Does Meso 2/3-butanediol have an internal mirror plane?

Figure 6.14 A 180° internal rotation of (2R,3S)-2,3-butanediol gives an eclipsed conformation that is achiral because it has a plane of symmetry (internal mirror plane). The existence of an achiral conformation (even an un- stable one) shows that (2R,3S)-2,3-butanediol is a meso compound.

What is 2 2 3 butanediol?
