Gas
Phase Core Excitation Database
corex_read-me.html last changed: 01-Jun-2025 (aph) What is this database ? This data base contains over 680 gas phase core excitation spectra of more than 400 pure compounds recorded using the dipole regime inner shell electron energy loss spectroscometer (ISEELS) at McMaster University from 1984 to the present. Typical uses of these spectra include: (i) helping to
identifying unknown species; (ii) reference spectra for quantitative
fitting spectra of mixtures, as encountered in X-ray or EELS spectromicroscopy.
The references to the spectra (both published and unpublished)
are given: The spectra are calibrated to well characterized secondary
standards using the values listed (CO,
CO2, N2, SF6, Ne). The spectra are accessed by either: A) select from the corex_index_flat
listing (no PHP) (use the browser
search capability to find species of interest) OR B) select from one of the three indices which
are generated from the data files THEN (i) identify the species of interest (ii) click on the data filename link (e.g. for N2
, the filename is nn-0cckk.os).
This will either: for approach A, click - display the text
file in the browser; for approach B, a
new window will be generated, as indicated below, allowing you to History Prior to the current version, the last version was posted
in June 2016. The latest version of the associated gas
phase core excitation bibliography was posted in June 2025,
as an update to the June 2016 version. Credits I thank all the undergraduate, graduate and postdoctoral fellows who used the McMaster dipole EELS spectrometers to measure the spectra reported in this database.
