Diatomic-py: A Python module for calculating the rotational and hyperfine structure of 1Σ molecules
Abstract
We present a computer program to calculate the quantised rotational and hyperfine energy levels of 1Σ diatomic molecules in the presence of dc electric, dc magnetic, and off-resonant optical fields. Our program is applicable to the bialkali molecules used in ongoing state-of-the-art experiments with ultracold molecular gases. We include functions for the calculation of space-fixed electric dipole moments, magnetic moments and transition dipole moments.
