maxwelllink.units module

maxwelllink.units.unit(from_unit, to_unit='au')

Return the conversion factor from one unit to another.

maxwelllink.units.wavelength_nm_from_omega(omega, units='cm-1')

Convert a photon frequency/energy (or wavelength) to a vacuum wavelength in nm.

Parameters:

• omega (float) – Photon frequency/energy in units, or a wavelength if units is "nm" or "um".

• units (str, default: "cm-1") – One of "cm-1", "eV", "au" (Hartree), "nm", "um".

Returns:

The vacuum wavelength in nanometers.

Return type:

float
