WebMay 19, 2024 · However, in TASK 7 you need to calculate the RDF only for water instead of the whole system. Since the glyala molecule contains two oxygen atoms itself, it is not reasonable to include these oxygen atoms of glyala if we are only interested in the O-O RDF for water. However, using VMD, the O-O RDF for the water can still be easily calculated. In … WebOct 10, 2024 · AIMD - RDF - PMF - pKa calculation? #1 by jinylee » Wed Oct 10, 2024 10:54 am I think I'm in a deep mis-understanding now. As a result of NVT calculations, we can easily draw RDF (radial distribution function), PMF (potential of mean-force) = -kB (boltzman-constant)*T*ln (RDF). Is this formula true?
