Reference Manuals for GPOP Components

Pre-processing tools
gpop1scf Preprocessing Tool for a Gaussian SCF/DFT-level frequency job output.   It extracts essential results needed by the other GPOP components and stores them in a GPOP format file.
gpop3tst Tool to modify a GPOP format file using information provided in a '.mod' file containing the energy and internal rotor specifications.
gpop3atm GPOP format file generator for atomic species.
gpop3mod (under construction) Forth-coming version of gpop3tst.
Thermodynamics / rate constant calculation tools
gpop4thf Calculation tool for thermodynamic functions.
tstrate Calculation tool for rate constants for reaction.
Diagnostics tools
gpop5vib Animation file generator for vibrational modes. (compatible with Free Wheel only)
gpop6irt Tool to calculate reduced moment of inertia of an internal rotor.
gpop6mrt Tool to calculate reduced moments of inertia of internal rotors and possible coupling between them.
introt Similar to gpop6mrt but can be used without GPOP format files.
