Zusammenfassung:	PCT No. PCT/GB92/00825 Sec. 371 Date Nov. 9, 1993 Sec. 102(e) Date Nov. 9, 1993 PCT Filed May 7, 1992 PCT Pub. No. WO92/19968 PCT Pub. Date Nov. 12, 1992.Organometallic compounds such as tricarbonyl-( eta 4-1,3-cyclo-hexadiene)lron(O) display an infrared spectrum which varies according to the solvent polarity, pH and similar factors. By comparing the wavenumber position and shape of the peak of a test spectrum with reference spectra by interpolation or extrapolation, information is obtained about the test sample, even a quantitative analysis in some cases. More than one organometallic compound may be used in one experiment (for double checking), and/or a mixture of analytes may be investigated, for obtaining information about the combination.
