sc::LinOPSimpleCo - The LinOPSimpleCo class describes an out-of-plane component of a linear bend internal coordinate of a molecule.
#include <simple.h>
Inherits sc::SimpleCo.
LinOPSimpleCo (const LinOPSimpleCo &)
LinOPSimpleCo (const char *refr, int, int, int, const SCVector3
&u)
This constructor takes a string containing a label, and three integers a, b,
and c which give the indices of the atoms involved in the linear angle abc.
LinOPSimpleCo (const Ref< KeyVal > &)
The KeyVal constructor. const char * ctype () const
Always returns the string 'LINIP'. double radians () const
Returns the value of the angle abc in radians. double degrees () const
Returns the value of the angle abc in degrees. double preferred_value
() const
Returns the value of the angle abc in degrees.
The LinOPSimpleCo class describes an out-of-plane component of a linear bend internal coordinate of a molecule.
The input is described in the documentation of its parent class SimpleCo. A vector, $s the keyword u, that is not colinear with either $ -
Usually, LinOPSimpleCo is used with a corresponding LinIPSimpleCo, which is given exactly the same u.
Designating the three atoms as $a$, $b$, and $c$ and their cartesian positions as $$, $nd $lue of the coordinate, $heta_o$, is given by
b} = ac{ - ac{ac{heta_o = i
- rccos ( b} dot
This constructor takes a string containing a label, and three integers a, b, and c which give the indices of the atoms involved in the linear angle abc. The last argument, u, is a unit vector used to defined the direction perpendicular to the direction in which distortion is measured. Atom numbering begins at atom 1, not atom 0.
The KeyVal constructor. This calls the SimpleCo keyval constructor with an integer argument of 3.
