The behaviour of this kernel in the presence and absence of local field effects is studied. The absorption spectra of poly-phenylene-vinylene has a bound excitonic peak which is well reproduced by the bootstrap kernel. Pentacene and picene, electronically similar materials, have remarkably different excitonic physics which is also captured properly by the bootstrap kernel.
