Unit conversion#

This module contains convenient unit conversion factors. Here, radians_per_fs_to_invcm, for example, can be used to convert an angular frequency in units of radians/fs to a wavenumber in 1/cm, as demonstrated by the code snippet below:

>>> # converting angular frequencies (omega) to wavenumbers in inverse cm
>>> import numpy as np
>>> omegas = np.linspace(0, 15, 100)
>>> frequencies_invcm = omegas * radians_per_fs_to_invcm
>>>
>>> # converting from inverse cm to meV
>>> frequencies_meV = frequencies_invcm / meV_to_invcm

In practice you can apply this conversion directly to, e.g., the frequencies of a DynamicSample object.
