Controlled Molecule Imaging Stark effect calculation code
CMI Stark effect calculation program
The CMIstark software package provides a library and enduser scripts to calculate, print, and plot the Stark energies of linear, symmetric, and asymmetric top molecules in DC electric fields. It utilizes the symmetry of the problem to minimize computation time, and most importantly, to provide correct adiabatic labels for all quantum states (e.g., high rotational energies and strong fields).
The program and code is documented in Comp. Phys. Comm. (2013), DOI: 10.1016/j.cpc.2013.09.001 and the published code is available at http://cpc.cs.qub.ac.uk/summaries/AEQS_v1_0.html.
