It was reported that the K/Cu-Zn-Fe oxides catalyst efficiently converted a mixture of COj and H2 into ethanol by Mitsubishi Gas Chemical and National Institute of Material and Chemical Research [1]. However, the catalyst was deactivated quickly during the reaction. To improve the catalytic life, an addition of various kinds of components was tried. It was found that the addition of Cr component to the catalyst prevented the deactivation of catalyst [2]. In this paper, we describe the effect of the addition of Cr component to the catalyst from the results of XRD analysis, transmission electron microscope observation (TEM), and energy-dispersive X-ray microanalysis (EDS) of the catalysts before and after the reaction.

Integrated Spectral DataBase System for Organic Compounds, National Institute of Materials and Chemical Research, Tsukuba, Ibaraki 305-8565, Japan. This database includes infrared, mass spectra, and NMR data (proton and carbon-13) for a number of compounds. 

Peter Lundberg, University of Umea, Sweden, has compiled a very complete list of educational NMR software. It is available from a number of sites, including http //atlas.chemistry.uakron.edu 8080/cdept.docs/ MAGNET/sware.html and the Bruker Web sites. http //www.aist.go.jp/RIODB/SDBS/menu-e.html Integrated Spectral DataBase System for Organic Compounds, National Institute of Materials and Chemical Research, Tsukuba, Ibaraki 305-8565, Japan.

In addition to the intensity, other properties such as polarization are concerned in optical rotatory dispersion and circular dichroism. The various processes give rise to different spectroscopic methods, as summarized in the Table 7.1. Various spectra (UV, IR, NMR and MS) of simple biomolecules can be accessed from Spectral Database Systems (SDBS) of the National Institute of Material and Chemical Research, Japan at http //www.sist.go.jp/RIODB/SDBS/menu-e.html.
