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

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

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.

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.
