In the same way the angular broadening of photoluminescence from the upper branch can be considered. Assume that E = E 0) in eqn (10.22). For zero detuning, the angular broadening for the upper branch is the same as for the lower branch. For the organic material of Ref. (10), we obtain q 48000 cm-1, q" 13600 cm-1. Thus, 9 30°, i.e. the angular distribution of photoluminescence from the upper branch is well noticeable. 

The first chemical transformations carried out with Cjq were reductions. After the pronounced electrophilicity of the fullerenes was recognized, electron transfer reactions with electropositive metals, organometallic compounds, strong organic donor molecules as well as electrochemical and photochemical reductions have been used to prepare fulleride salts respectively fulleride anions. Functionalized fulleride anions and salts have been mostly prepared by reactions with carbanions or by removing the proton from hydrofullerenes. Some of these systems, either functionalized or derived from pristine Cjq, exhibit extraordinary solid-state properties such as superconductivity and molecular ferromagnetism. Fullerides are promising candidates for nonlinear optical materials and may be used for enhanced photoluminescence material.
