Dyakonov tensor

A = J —J f. Here the Dyakonov tensor <1>q characterizes the polarization of the registered light. In deriving Eq. (2.24) the properties of the 17-functions were used, as previously in the case of Eq. (2.21) and according to (A.13) and (B.4). It may thus be seen from (2.24) that only the multipole moments bpQ of rank K < 2 have any direct effect on the intensity and polarization of molecular fluorescence. This latter assertion also holds in the case where multipole moments of rank higher than K = 2 are created in the excited state (6) in the case of absorption of sufficiently intensive light. 

Let us consider the transition (J" = 1 - J — 1) which is excited by linearly polarized light, the polarization vector E being directed at angles 6, (p Fig. 5.8. Substituting the values of the Dyakonov tensor from Table 2.1, and the coefficients from Table 5.2 into the system of equations...
