37.9550.Dorofeeva O.V., 1989These statistically calculated values were obtained using force field approximation for polycyclic aromatic hydrocarbons to estimate the needed vibrational frequencies (see also [ Dorofeeva O.V., 1986, Moiseeva N.F., 1990]). These functions are reproduced in the reference book [ Frenkel M., 1994].
