Stark Effect in Hydrogen Steiner, E. Abstract. Publication: Journal of Chemical Physics. Pub Date: July 1962 DOI: 10.1063/1.1701349 Bibcode: 1962JChPh..37..454S Because the field is weak, the elliptical orbit may be treated as a dynamical element itself, variations in its shape and orientation depicting the classical Stark effect. The behavior of this orbit is then correlated with the quantum mechanical description of the first‐order Stark effect in hydrogen, a subject that is included in most introductory courses in quantum mechanics.
