What is the relationship between the Rydberg constant and Hartree energy?
-
One Rydberg constant equals half a Hartree energy, symbolizing that Hartree energy is twice the Rydberg energy scale.
-
Why convert from Rydberg constant to Hartree energy?
-
Converting helps relate atomic spectral line energies to the common energy unit used in quantum chemistry calculations, facilitating comparisons of electronic energies.
-
Can this converter be used for experimental energy measurements?
-

Key Terminology
-
Rydberg constant
-
A fundamental constant defining the limiting wavenumber for hydrogen-like atomic transitions and associated with ionization energy in atomic physics.
-
Hartree energy
-
The atomic unit of energy used in quantum chemistry, equal to twice the Rydberg energy, providing a natural scale for electronic structure calculations.
-
Infinite nuclear mass approximation
-
An idealized condition assuming the nucleus has infinite mass, simplifying the calculation of atomic energy levels.
