.hess file - mass-weighted? units?


Clicked A Few Times
Hi all,

I recently generated the hessian using the following lines in the nwchem input file,

set gen_hess:actlist 1:28
set hessian:compress .true.
task dft hessian numerical

The .out or .hess files unfortunately do not mention if the hessian matrix elements are mass-weighted and the units, and so I am wondering if the unit of the elements in the .hess file is hartree/bohr^2, and if it is not mass-weighted?

Thanks!
