Subject: AMBER: force field

Dear All,

As I have seen in the literatures, the feature of force field of AMBER, for
example bond term is

summation { Kb(l-l0)^2}

whereas in some book it is

summation {Kb/2(l-l0)^2} , i.e. there is a term of 1/2

Could you please tell me why they are different?

Thank you very much in advance for your kindness.

Best Regards,
Hungie
