Abstract: The present invention provides a method for testing and fitting the dihedral angle parameters in force field. The method first generates some representative conformations, and then compares the results of force field and quantum mechanics methods using these structures. If the results meet the predefined standards, the process ends; otherwise the molecule will be cut into small-size molecular fragments with only one flexible dihedral angle in each fragment. The dihedral angles will be scanned. And results of force field and quantum mechanics will be compared for each scanned flexible dihedral angle to find out those that do not meet the standards, and their parameters will be selected for further fitting. After new dihedral angle parameters are obtained, apply them to the original series of conformers of the whole molecule for validation. If results meet the standards, complete the whole process of testing and fitting poorly performing dihedral angle parameters.
