<div dir="ltr">Hi, Monu,<div><br></div><div>You can run a molecular dynamics simulation at room temperature, for several picosecond, and then you can plot the radial distribution function, between your guest molecule and the MOF, by doing this you would have a general picture of the free energy surface of your guest molecule in the MOF. Then based on the free energy minima structures, you can start to optimize your guest-MOF complex structure. (the free energy surface may be different from the potential energy surface, but at least by doing MD simulation and calculating the free energy surface based on radial distribution function, you can have a basic idea about the free energy surface, which should not be quite different from potential energy surface).</div><div><br></div><div>Regards,</div><div><br></div><div>Fangyong</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Jan 12, 2021 at 7:20 PM Monu Joy <<a href="mailto:monuj...@gmail.com">monuj...@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div style="font-family:verdana,helvetica,sans-serif;font-size:13px"><div dir="ltr">Hi there</div><div dir="ltr"><br></div><div dir="ltr"><div><div dir="ltr">I have a general question: I would like to find out the global minimum of a guest molecule within the pore of a MOF.
