  2. Slater-type orbital - Wikipedia

    en.wikipedia.org/wiki/Slater-type_orbital

    STOs have the following radial part: =where n is a natural number that plays the role of principal quantum number, n = 1,2,...,; N is a normalizing constant,; r is the distance of the electron from the atomic nucleus, and

  3. Node (physics) - Wikipedia

    en.wikipedia.org/wiki/Node_(physics)

    Atomic orbitals are classified according to the number of radial and angular nodes. A radial node for the hydrogen atom is a sphere that occurs where the wavefunction for an atomic orbital is equal to zero, while the angular node is a flat plane. [4] Molecular orbitals are classified according to bonding character. Molecular orbitals with an ...

    The one-dimensional form of ESPRIT can be applied if the weights have the form , = (), whose phases are integer multiples of some radial frequency. This frequency only depends on the index of the system's input, i.e. k {\textstyle k} .

    Some nodes occur at particular angles (relative to an arbitrary origin) and are known as angular nodes, and some occur at particular radii from the nucleus and are known as radial nodes. The number of radial nodes for a given orbital is given by the relationship n-l-1 where n is the principle quantum number and l is the orbital angular momentum ...

    One particle: N particles: One dimension ^ = ^ + = + ^ = = ^ + (,,) = = + (,,) where the position of particle n is x n. = + = = +. (,) = /.There is a further restriction — the solution must not grow at infinity, so that it has either a finite L 2-norm (if it is a bound state) or a slowly diverging norm (if it is part of a continuum): [1] ‖ ‖ = | |.

  7. Atomic orbital - Wikipedia

    en.wikipedia.org/wiki/Atomic_orbital

    The Slater-type orbital (STO) is a form without radial nodes but decays from the nucleus as does a hydrogen-like orbital. The form of the Gaussian type orbital (Gaussians) has no radial nodes and decays as e − α r 2 {\displaystyle e^{-\alpha r^{2}}} .

    A radial function is a function : [,).When paired with a norm on a vector space ‖ ‖: [,), a function of the form = (‖ ‖) is said to be a radial kernel centered at .A radial function and the associated radial kernels are said to be radial basis functions if, for any finite set of nodes {} =, all of the following conditions are true:

  9. Orbital node - Wikipedia

    en.wikipedia.org/wiki/Orbital_node

    In the case of objects outside the Solar System, the ascending node is the node where the orbiting secondary passes away from the observer, and the descending node is the node where it moves towards the observer. [5], p. 137. The position of the node may be used as one of a set of parameters, called orbital elements, which
