Broadening = 0.01000000 Ry
Output file name: CH4.plot_chi.dat
Output file name for the oscillator strength S CH4.plot_S.dat
chi_i_j: dipole polarizability tensor in units of e^2*a_0^2/energy
S: oscillator strength in units of 1/energy
S(\hbar \omega) = 2m/( 3 \pi e^2 \hbar) \omega sum_j chi_j_j
S(\hbar \omega) satisfies the f-sum rule: \int_0^\infty dE S(E) = N_el
Functions are reported in \hbar.\omega Energy unit is (Ry)
