Embodiment Construction
[0051] Such asfigure 1 and figure 2 As shown, the potential energy surface scanning method for molecular conformation space analysis of an embodiment of the present invention includes the following steps:
[0052] Step S101, Judgment of Adjacent Dihedral Angles: Judging whether a given analysis has adjacent dihedral angles (such as figure 2 shown);
[0053] Step S103, QM coupling judgment: if it is judged that there are adjacent dihedral angles, it is judged whether adjacent dihedral angles are coupled through QM (Quantum Mechanics, Quantum Mechanics) calculation,
[0054] If the QM calculation judges that there is no coupling, then proceed
[0055] Step S105, one-dimensional potential energy scanning: the scanning limits one dihedral angle to change from -180° to +180° at set intervals, and the other dihedral angles are not limited, so as to obtain the one-dimensional potential energy surface of the molecule;
[0056] If the QM calculation judges the coupling, proceed
