Abstract: The EXAFS data obtained by employing laboratory set-ups using X-ray films as detectors, has been analyzed qualitatively and empirically to yield information about molecular structure and average bond length. Such photographic data has been analyzed by Fourier transforming and fitting with theoretical standards using the available software packages in the present paper. The results obtained have been compared with those obtained from another laboratory set-up employing rotating anode X-ray tube with scintillation detector and also with the results obtained from synchrotron EXAFS set-ups using ionization chambers and CCD as detectors. By taking two examples, one of the Cu metal foil spectra, in which EXAFS oscillations are strong and another of the copper complex, viz., Cu(en)2(ONO2)2 [en = ethylenediamine] spectra, in which EXAFS oscillations are weak, it has been shown that the commonly available laboratory EXAFS set-ups employing photographic method of registration can also be used for easy and quick determination of the local structures at least for the first two coordination shells.
