Question

Any body knows how to interpretation of XPS spectra!!!

Answer 1

XPS spectra means?

Answer 2

@heena
XPS = X-ray photoelectron spectroscopy

See the image below:

Answer 3

hey thanks for the image u knw i read abu thi technique but never tried to have a look of its image ^.^

Answer 4

@chmvijay

Unless you can provide a graph of # of electrons v. binding energy... This can't be answered.

You simply read the peaks and match to the orbital levels. You know, like the stuff you did in Chemistry 1? example:

\[1s^2 2s^2 2p^6 3s^2 3p^6 = [Ar] \]

Answer 5

If you need more information, you need to look up the approximate orbital lengths for each known element you need to read. This is some table stuff that if you're into reading these spectrographs you'll NEED to have handy, or have a computer's software doing it for you.

The formula for this is:
\[Energy = \frac{Z*e^2}{a}\]
Z = atomic #, aka. # of protons
a is unknown without the tables which are from experimental measurement
