[gmx-users] Re: TI and heavy H

[reich at mpikg.mpg.de]

Hi Mark,

to create heavy hydrogens 3amu are transferred from the respective N to
the respective H. I do not need to conserve mass in TI -and there wouldn't
actually be a conservation in mass no matter whether I transfer mass to a
dummy atom or not. I am just worried about choosing the correct mass so
that I can sample the correct momentum space.

Best

Luther
