47.2 Printing options (PRINT)


This directive can be used to control the output:

The following options can be given:

Print the force constant matrix (hessian) i.e. the second derivative matrix of the energy and the mass weighted hessian matrix.
Print low vibrational frequencies (i.e. the 5 or 6 frequencies belonging to rotations and translations) and their normal modes (default; LOW=-1 suppresses the print).
Threshold for printing low vibrations in cm$^{-1}$ (default 150). If a value $>0$ is given, frequencies below this value are not printed. 2018-03-24
