UNEX is a program environment for investigation of molecular structure. It has been created by the Vishnevskiy Group. In this project we develop new and existing experimental methods and combine them to increase accuracy and precision of results. At the current stage the full support for the gas electron diffraction (GED) method 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.
