UNEX is a programming environment for investigation of molecular structure. We develop new and existing experimental methods and combine them to increase accuracy and precision of results. At the current stage the full support of gas electron diffraction (GED) investigations is provided, from the calibration of instruments and data reduction to the refinement of molecular structure. Additionally, rotational constants can be used solely or in combination with GED data for determination of molecular geometry.
