Detailed Description

The SetIntCoor class describes a set of internal coordinates.

It can automatically generate these coordinates using a integral coordinate generator object (see the IntCoorGen class) or the internal coordinates can be explicity given.

The following is a sample ParsedKeyVal input for a SetIntCoor object.

  setintcoor<SetIntCoor>: [
    <SumIntCoor>: (
      coor: [
        <StreSimpleCo>:( atoms = [ 1 2 ] )
        <StreSimpleCo>:( atoms = [ 2 3 ] )
        ]
      coef = [ 1.0 1.0 ]
      )
    <BendSimpleCo>:( atoms = [ 1 2 3 ] )
  ]

Constructor & Destructor Documentation

◆ SetIntCoor()

sc::SetIntCoor::SetIntCoor ( const Ref< KeyVal > & )

The KeyVal constructor.

generator

A IntCoorGen object that will be used to generate the internal coordinates.

i

A sequence of integer keywords, all $i$ for $0 \leq i < n$, can be assigned to IntCoor objects.

Member Function Documentation

◆ guess_hessian()

virtual void sc::SetIntCoor::guess_hessian ( Ref< Molecule > & ,
RefSymmSCMatrix &  )
virtual

Create an approximate Hessian for this set of coordinates.

This Hessian is a symmetric matrix whose i'th diagonal is the force constant for the i'th coordinate in the set.

◆ save_data_state()

void sc::SetIntCoor::save_data_state ( StateOut & )
virtual

Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them.

This must be implemented by the derived class if the class has data.

Reimplemented from sc::SavableState.
