# Atomic orbitals 7f wave functions

This page contains movies depicting the 7f wave functions and their nodal structures. In all cases the green zones are where the 7f wave function has positive values and the white zones denote negative values. See the 7f electron density page for movies depicting the 7f electron_density and nodal structures.

In each case the graph on the left is a surface plot of ψ7f on a slice drawn through the nucleus. They show the wave function collapsing on to the plane so as to show the nodal struction on the plane. The plot on the right shows values along a single line drawn through the nucleus. The points on the line plot or the surface plot where the colour changes from one to the other represent the points at which the orbital nodal spheres crosses the line or surface.

Each of the 7f orbitals has three planar nodes or conical nodes. The 7f orbitals have three spherical nodes but the higher f-orbitals (8f, 9f, ... ) have more while the lower orbitals ( 4f, 5f, and 6f) have fewer.

## 7fz3, 7fx3, and 7fy3 orbital wave functions

Movie depicting the 7fz3 wave functions (ψ7fz3)2. The z-axis lies from left to right. The 7fx3 and 7fy3 orbitals are identical in appearance but orientated along the x and y axes respecively. The 7fz3 orbital has one planar and two conical nodes. The 7f orbitals have three spherical nodes but the higher f-orbitals (8f, 9f, ... ) have more while the lower orbitals ( 4f, 5f, and 6f) have fewer.

## 7fxz2 and 7fyz2 orbital wave functions

The first image shows a two-dimensional wave function plot of the 7fxz2 orbital (across the x=0 plane). The 7fyz2 wave function is identical in appearance but the orbital is related by a rotation by 90° about the y-axis.

## 7fxyz and 7fz(x2-y2) wave functions

Movie depicting the 7fxyz wave function (ψ7fxyz)2. The left image shows a two-dimensional wave function plot of the 7fxyz orbital (across the x=y plane). The right image is along the x=y, z=0 line. The 7fxyz and 7fz(x2-y2) are related to each other by a 45° rotation about the z-axis.

## 7fy(3x2-y2) and 7fx(x2-3y2) wave functions

The first image shows a two-dimensional wave function plot of the 7fx(x2-3y2) orbital (across the z=0 plane, x axis pointing right). The 7fy(3x2-y2) orbital is identical in appearance but rotated by 90° about the vertical z-axis.
