I am not sure what exactly you mean by rigidify? Amber can freeze part of your system. See the ibelly keyword.

I'm investigating into the stability of molecules upon visible and ultraviolet light. As it is not easy to predict properties of the excitation state accurately, several questions must be figured out: (1) Theoretical levels. Trying to find out whether the luminous energy can be absorbed, I am eager to know how to predict the energy gap of the excitation-state molecular orbital. So far the Configuration Interaction approach (CI-Single), CASSCF (Complete Active Space Multiconfiguration SCF), and TD-DFT can be performed by Gaussian for this task. But because of the limitation of computational resources and the possible convergence problems, each method is suitable for some specific systems. Could anyone compare them and figure it out? And could anyone recommend other theoretical approaches? (2) Application problems. Even if we obtain the energy gap of the excitation-state molecular orbital with acceptable accuracy, the absorption peak of specific compound may not equal to it, not to mention the energy gap of the ground-state molecules. So is there any other solution to predict the wavenumber of absorption peak? Thanks a lot.

I'm trying to use this program in order to classify vdW interactions - mainly HBs. As we know it is possible based on the generally accepted rules concerning the values of ED and its Laplacian at the BCPs. I've started with the test case - water dimer {mp2/6-31+G(d)}, since there is HB for sure, but I found a negative value of Laplacian. In the literature, there are certain criteria for HB: ED (0.002-0.035 au) Laplacian (0.024-0.139 au) In my case these values are 0.029 and -0.023, respectively. ED is OK but Laplacian is not. Could anyone comment on that? What should be done, step by step? In the main menu I can choose between ED and Laplacian and obtain different values. Which of them should be taken in my case? I will appreciate your help.
