Dipole oscillator strength distribution DOSD

Many methods for the evaluation of from equation ( Al.5.20) use moments of the dipole oscillator strength distribution (DOSD) defined, for molecule A, by... 

The results and their statistical analysis are collected in Table 1 for a set of small molecules taken from the database compiled by Tkatchenko and Scheffler [16], as used in [58]. The experimental dispersion coefficients have been determined from dipole oscillator strength distributions (DOSD) [59-71]. The percentage errors of some of the methods (LDA[M], PBE[M], RHF[M] and RSHLDA[M]) are shown in Fig. 3. 

The set of dipole oscillator strengths fno, defined in Eq. (7.69), is often called the dipole oscillator strength distribution (DOSD). Summed over all excited states, bound as well as continuum states, they are related to several other molecular properties, as will be shown in the following. One defines two types of energy-weighted moments of the dipole oscillator strength distribution ...
