Some unofficial phone apps appear to be using GameFAQs as a back-end, but they do not behave like a real web browser does.Using GameFAQs regularly with these browsers can cause temporary and even permanent IP blocks due to these additional requests.

The ZEKE Database by Edward Schlag at the Institute for Physical and Theoretical Chemistry, Technical University of Munich lists high precision ionization energies determined by ZEKE. The NIST XPS Database contains ionizations energies measured by solid-state XPS in tabular format with extensive references.ĭatabase of Molecular Photoelectron Spectra by Leif Karlsson at the Department of Physics at Uppsala University. Ionization energies are given in tabular format with extensive references. The data presented here is derived from a variety of methods, including photoelectron spectroscopy. The NIST Chemistry WebBook contains ion thermochemistry data, including ionization energies. Other Online Compilations of Photoelectron Spectra and Ionization Energies The energy scale is calibrated to a precision of better than 0.02 eV. The typical resolution during data collection is 0.01-0.02 eV. Most data were collected with a He(I) discharge source, although some of the spectra shown were collected with the He(II) line so that ionizations above 20 eV could be shown. Experimental DetailsĪll of the spectra in the database at this time were collected using the instrumentation in the Center for Gas-Phase Electron Spectroscopy at The University of Arizona. The details page contains links to jpg images of spectral plots and to txt files containing x,y data in the format used by the program WinFp.

To see more information on any entry click the name of the molecule. The page lists the spectra currently in the database sorted by type of molecule. To view the contents of the database click the button " Database Contents" located at the top and bottom of this page. Several other databases that provide tables of ionization energies are listed below. The purpose of this database is to present photoelectron data in the format of spectral plots and data files. This is a work in progress that currently only contains a few entries that will (hopefully) expand as time allows. This database contains valence photoelectron spectra of neutral organic, inorganic, and organometallic molecules in the gas phase.
