Gas
Phase Core Excitation Database
corex_read-me.html last changed: 31-May-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 tinner shell electron energy loss spectroscometer (ISEELS) at McMaster University from 1984 to the present. Typical uses include: (i) helping to identifying unknown
species; (ii) reference spectra for 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to the spectra (both published and unpublished) are given The spectra are calibrated to well characterized secondary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 (CO, CO2, N2, SF6, Ne).
The spectra are accessed by either: A) select from the corex_index_flat
(no PHP) (use the browser search capability
to find species of interest) OR B) select from one of the three indices THEN (i) identify the species of interest (ii) click on the 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, pop-up
a new window will be generated allowing you to History Prior to the current version, the last version was posted
in June 2016. The latest version of the gas
phase core excitation bibliography was posted 31-Mar-2025, as
an update to the June 2016 version. Credits I thank all the undergraduate, graduate and postdoctoral fellows who used the McMasterr dipole EELS spectrometer to measure the spectra reported in this database. The spectra contained in this data base were recorded by one or more of the following: Undergraduate students: (bold - B.Sc. theses) T.
