BIBLIOGRAPHY AND DATABASE OF INNER-SHELL EXCITATION-SPECTRA OF GAS-PHASE ATOMS AND MOLECULES

An annotated bibliography of articles consisting of theoretical or exp erimental studies of inner shell (core) excitation of atoms or molecul es is provided. A computer database consisting of 374 spectra of 191 m olecules has been assembled. All of these spectra were recorded by ele ctron energy loss spectroscopy (EELS) in the electric dipole regime. T he database spectra are presented as both raw data and after conversio n of the isolated core excitation signal to an absolute oscillator str ength (f-value) scale. An improved scheme for deriving absolute oscill ator strengths is described and tested. Instructions are provided for accessing the database with the file transfer protocol (FTP) over the Internet. Such spectra may be useful for fingerprint comparisons, comp arisons to calculations, etc. In the future the database will be exten ded to include data from other sources, including gas phase photoabsor ption spectra recorded by direct optical means, as well as critical co mmentary on data base entries.
