NAME
EyeMopacVib
DESCRIPTION
This module reads a Mopac output force file and generates
the vibration of the selected eigenvalue. Each step in the
vibration is a Chemistry Pyramid. The connectivity of the
resting molecule is determined by a vdw radius test and does
not change during the vibration. In order for the module to
determine the correct number of eigenvalues, the Mopac input
file should contain both the keywords FORCE and LARGE. Mopac
versions 5, 6 and 93 are supported.
WIDGETS
Filename -- Text
Filename of Mopac output force file.
Element -- Text
Filename of reference chemical data. This file includes
the following properties for all atoms : atom number,
covalent radius, Van Der Waals radius, maximum
number of bonds.
Cycles -- Dial
The selected cycles of vibrations.
Increments -- Dial
Number of increments between resting molecule and
displacement.
Eigenvalue -- Dial
The selected eigenvalue to be analyzed.
Coordinate Analysis -- Option Menu
(Normal, Mass-weighted, Eigenvectors). The selected
vibration mode.
Multiplier -- Dial
Enhances or dampens the displacement.
OUTPUTS
Molecule -- Pyramid
(n-layer, optional-baseLat, n-D compression, n-
compression type). The output is a Chemical-based
pyramid. This pyramid has 2 layers of lattices. The
base layer (0) contains the bond order and 2 atom
numbers that comprise the bond. The next layer (1),
contains the connectivity information, atom data, and
the cartesian coordinates. Eact atom has 4 data
variables: ID, element number vdw radius, and colour
number.
KNOWN PROBLEMS
Might not work properly without the keyword "LARGE".
