Units of orbital angular momentum QM?

Click For Summary
SUMMARY

The discussion centers on determining the units of orbital angular momentum in quantum mechanics, specifically for a hydrogen atom in the 3d state. The correct units for orbital angular momentum are established as Joule-seconds (J·s) or equivalently kg·m²/s. The confusion arises from differentiating these units from other physical quantities, emphasizing the importance of understanding dimensional analysis in quantum mechanics.
