Dear vmd users,
I am using the fftk toolkit to generate parameters
for my molecule. I have optimized the molecule and performed hessian
calculations. When I am trying to generate bond parameters, the equilibrium
bond length and K (force constant) values obtained are as shown below:
!atom type Kb b0
!
C C4 0.739 -0.001
C C2 0.153 0.000
I could not understand why the values are too low. The initial parameter
file contains 0 values are Kb abd b0. Could please suggest some of the
possible reasons for the observed weird values for Kb and bo.
Thank your very much for a reply in advance
Regards,
Mohan Maruthi
