PROGRAM:

NAME


gausssum - parses the output of a Gaussian, GAMESS or HyperChem job

SYNOPSIS


gausssum [filename]

DESCRIPTION


gausssum parses the output file of a Gaussian, GAMESS or HyperChem computational chemistry
job to extract useful information. It uses gnuplot(1) to graphically display of the
output. GaussSum can do the following: (Gau=Gaussian, GAM=GAMESS, Hyp=HyperChem)

· display all lines containing a certain phrase (any)

· follow the progress of the SCF convergence (Gau,GAM)

· follow the progress of a geometry optimisation (Gau,GAM)

· extract molecular orbital information, including contributions of groups of atoms
to the molecular orbitals (Gau,GAM)

· plot the density of states spectrum (and the partial density of states, in the case
of groups of atoms) (Gau,GAM)

· plot the crystal orbital overlap population (COOP) spectrum, which gives
information on the bonding/anti-bonding nature of an overlap between atoms/groups
(Gau,GAM)

· extract information on the UV-Vis transitions (Gau,Hyp), including the change in
the charge density of groups of atoms (Gau)

· plot the UV-Vis spectrum (Gau,Hyp) and the circular dichroism spectrum (Gau)

· automate the creation of electron density difference maps, which visually show the
change in charge density associated with a given electronic transition (Gau)

· extract information on IR (Gau,GAM) and Raman vibrations (Gau)

· plot the IR and Raman spectra, which may be scaled using general or individual
scaling factors (Gau)
