## 3. Why do we say that s orbitals have zero angular momentum? - Socratic

Sep 8, 2017 · The angular momentum of any s orbital is zero, since the wave function for an s orbital has no angular dependence.

The angular momentum of any s orbital is zero, since the wave function for an s orbital has no angular dependence. In other words, recall that angular momentum gives rise to irregular shapes of a given atomic orbital. Well, all s orbitals are spherically symmetric, so angular momentum has no influence on the shape. Consider some of the s orbital wave functions: psi_(1s)(r,theta,phi) = 1/sqrtpi (Z/a_0)^(3//2)e^(-Zr//a_0) psi_(2s)(r,theta,phi) = 1/(4sqrt(2pi)) (Z/a_0)^(3//2)(2 - (Zr)/a_0)e^(-r//2a_0) psi_(3s)(r,theta,phi) = 1/(81sqrt(3pi)) (Z/a_0)^(3//2) (27 - 18 (Zr)/a_0 + 2((Zr)/(a_0))^2)e^(-Zr//3a_0) If you look closely, there is no theta or phi anywhere in these wave functions. As a result, the orbitals they describe are perfect spheres, having zero angular momentum.

Photons can carry angular momentum, not only due to their spin, but also due to their spatial structure. This extra twist has been used, for example, to drive circular motion of microscopic particles in optical tweezers as well as to create vortices in quantum gases. Here we excite an atomic transition with a vortex laser beam and demonstrate the transfer of optical orbital angular momentum to the valence electron of a single trapped ion. We observe strongly modified selection rules showing that an atom can absorb two quanta of angular momentum from a single photon: one from the spin and another from the spatial structure of the beam. Furthermore, we show that parasitic ac-Stark shifts from off-resonant transitions are suppressed in the dark centre of vortex beams. These results show how light’s spatial structure can determine the characteristics of light–matter interaction and pave the way for its application and observation in other systems. The spatial structure of vortex laser beams associates angular momentum to photons, which, in addition to their spin, can be used to tailor light-matter interactions. Here, the authors excite an atomic transition with a vortex laser beam, showing that the transfer of angular momentum modifies selection rules.

## FAQs

### What is the orbital angular momentum of an S electron? ›

The orbital angular momentum of an electron in any s - atomic orbital is **zero**.

**Why orbital angular momentum of S is zero? ›**

The angular momentum of any s orbital is zero, since **the wave function for an s orbital has no angular dependence**.
