Here the one-dimensional semiconductor namely bis (dimethyiglyoximato) Ni?? is hydrogen bonded with 6 highly polarizable dyes which are Para red, Congo red, Direct red, Bismark brown, Evans blue and Trypan blue. The hydrogen bonding was verified with FTIR spectroscopy. FTIR specra also reveal modification of absorption edges by exciton-phonon coupling there are threshold energies for the formation of free excitons and electron-hole pairs with phonon emissions in the intrinsic absorption edge spectrum. The remainder absorption at the value of the band gap is proportional to the exciton ionization energy in both direct and indirect excitons. This remainder absorption increases with the increase in the number of phonon bands in the absorption edge.

The Fourier '“ transform infrared spectra of complexes of TEMPO free radical with organic acceptors like TCNE, DDQ, TCNQ, Chloranil has been studied. Some of them have ferro or antiferromagnetic properties at very low temperatures. From FTIR spectra, these complexes are found to be small band-gap semiconductors. They are interpreted as Hubbard semiconductors having non-universal band gap. They also show either asymmetric or symmetric Gaussian band revealing electronic delocalization. They are expected to be paramagnetic.
