Which of the following elements can be detected by XPS? - correct answer Lithium and
boron
Ionizing radiation consists of what type of radiation/rays/waves - correct answer gamma
rays and x-rays
Which of the following spectroscopies is/are suitable for studying materials on surfaces?
- correct answer XPS and UPS
Nuclear magnetic resonance spectroscopy can be used to study which type of atoms? -
correct answer 1H
Which type of wavelength in UV V spectroscopy is absorbed by easily excited
electrons? - correct answer longer wavelengths
Which of the following are excited in ultraviolet photoelectron spectroscopy? - correct
answer valence electrons
PES uses which type of electromagnetic radiation? - correct answer ultraviolet and x-
rays
When does absorption occur in infrared spectroscopy - correct answer when the
frequency of the electromagnetic radiation equals the vibrational frequency of a
molecule
How is a spectrum obtained in NMR spectroscopy? - correct answer Low-frequency
radio waves bombard the atom and cause nuclei in a low spin state to move to a higher
spin state.
