Question

In general, what would you do to calculate the spectrum intensities in Atomic Absorption, Auger and X-ray photoelectron spectroscopies?

Answer #1

How can you differentiate Auger Peaks from photoelectron
peaks in an XPS spectrum? Explain the theory.

The spectrum of a star has dark absorption lines of
helium superimposed on a continuous spectrum. What can you conclude
from this?
a The star is made up of helium
b There is a great deal of helium in the earthâ€™s atmosphere
c The dark lines have absorbed helium
d The light from the star has passed through a cloud of
helium
Estimate the wavelength of the red line in
oxygen.
Which of the following regions is the
widest?
a....

What is the general description for obtaining an NMR
spectrum and why do you need to use deuterated solvents and
Internal standard like TMS?

For Atomic Absorption Spectroscopy and Atomic Emission
Spectroscopy, one method can do multi-element while the other can
only do single element analysis. Which method would be preferred
for determining concentration of a known contaminant in a complex
matrix & why?

What type of gas would create an absorption spectrum? [pick best
answer]
A cool gas in front of an even lower temperature gas
A high temperature gas in front of a low temperature gas
A gas which contains at least 50% hydrogen
Any type of gas can create absorption spectra
A cool gas in front of a higher temperature gas

The atomic line spectrum of hydrogen contains a line in the
near-UV spectrum that corresponds to an electron transitioning from
an n = 7 orbital to an n = 2 orbital. What is the energy of the
emitted photons that produce this line?
I know the answer is 5.00 x 10^-19 J, I'm just unsure on how to
go about solving it. Please give any equations used and where the
numbers come from so I can try other problems on...

A series of line in athe spectrum of atomic hydrogen lie at the
frequencies shown below. What is the frequencey of the next line in
the series? Explain how you reach your answer.
4.5669 X 1014 s-1
6.1653 X 1014 s-1
6.8905 X 1014 s-1

1. Given values of two peaks on a GC spectrum, how do you
calculate the % of each product?
2. Given a GC Spectrum, how do you identify the major and
minor
products?

How do you calculate the relative atomic mass of an element
given the abundances with no calculator?

Describe with a diagram what you would expect to be the
differences between a powder x-ray diffraction (XRD) spectrum for
Si (diamond structure) and SiC.
