WebNote: At this point you are not telling CHARMM what the bond lengths and angles are, you are simply declaring that certain bonds and angles exist 3. Define the atom types. For water you require hydrogen and oxygen atom types with masses of 1 and 16, respectively. To define these two atom types in the RTF, type in the lines: MASS 1 H 1.0 !

WebMass records in a MMFF-capable rtf file must also be augmented to add the atomic symbol for each CHARMM atom type after the atomic mass entry. Note that MMFF-capable rtf files are back compatible. That is, such rtf files can equally well be used for calculations that utilize the CHARMM force field. http://mackerell.umaryland.edu/charmm_ff.shtml WebCHARMM (Chemistry at HARvard Macromolecular Mechanics) is a both a set of force fields and a software package for molecular dynamics simulations and analysis.
