Actual program output specific to a certain calculation starts with a statement of the program version, Gaussian revision (here B.03), system software (here LINUX), and the current date. Subsequently the keywords used in the input file are repeated together with other general settings such as the amount of main memory needed for the calculations (here 48MB), and the location of a binary checkpoint file for storage of important results (here /scratch/test1.chk). The "scf=tight" keyword used here specifies tight criteria for the energy calculation and the quantum mechanical method used is "HF/6-31G(d)".

The keywords are transformed by Gaussian into a sequence of subroutine calls termed "links". The links are given together with the corresponding options set for each link in a proprietary format. Provided that the "#P" option is used in the input file, Gaussian prints out elapsed CPU times after leaving a link.

In link101 the program reads in or retrieves from the checkpoint file the structure of the system together with other parameters and prints the structure (in a slightly modified format) together with overall charge and spin multiplicity and the comments supplied in the input file. It is good practice to include the name of the input file in the comments of the job. The system chosen here is formaldehyde in its electronic ground state.

Link202 determines, among others, the symmetry of the system, decides on the symmetry properties that will be used in the actual quantum mechanical calculations and rotates the molecule such that the center of mass is located in the origin of the cartesian coordinate system, the principal axis (so it exists) points along the z-axis, and the principal plane of symmetry (so it exists) is located in the yz-plane. The resulting orientation is printed as "Standard orientation", which serves as the reference description for all information regarding the wavefunction and first and second derivatives of the energy with respect to structural parameters.
