Answer: (b).when the frequencies match exactly
Question 3. Which of the following components of a monochromator is the dispersing element?
  1.    The collimating lens
  2.    The entrance slit
  3.    The diffraction grating
  4.    None of these
 Discuss Question
Answer is Option C. -> The diffraction grating
Answer: (c).The diffraction grating
Question 4. Vibrational spectroscopy is
  1.    a large mass on a weak spring
  2.    a flashlight through a prism and shake it
  3.    a class of spectroscopic techniques which analyzes molecular motions
  4.    an Infrared spectroscopy
 Discuss Question
Answer is Option C. -> a class of spectroscopic techniques which analyzes molecular motions
Answer: (c).a class of spectroscopic techniques which analyzes molecular motions
Question 5. Why are rotational transitions of little use to a spectroscopist?
  1.    Because the energy required to induce a rotational transition is so small that it cannot be measured
  2.    Because rotational transitions are extremely rare
  3.    Because, in liquids and solids, spectral lines corresponding to rotational transitions are broadened as the result of molecular collisions and other interactions
  4.    All of the above
 Discuss Question
Answer is Option C. -> Because, in liquids and solids, spectral lines corresponding to rotational transitions are broadened as the result of molecular collisions and other interactions
Answer: (c).Because, in liquids and solids, spectral lines corresponding to rotational transitions are broadened as the result of molecular collisions and other interactions
Question 6. All hydrogen atoms
  1.    have the same resonance frequency
  2.    resonate at different frequencies depending on their environment.
  3.    are attached to carbon
  4.    resonate at about the same frequency as carbon
 Discuss Question
Answer is Option B. -> resonate at different frequencies depending on their environment.
Answer: (b).resonate at different frequencies depending on their environment.
Question 7. What is the name given to the relaxation process due to an interaction between an excited nucleus and the magnetic fields caused by nuclei in molecules moving around in the sample?
  1.    Spin - lattice relaxation
  2.    Spin - spin relaxation
  3.    Spin - spin - spin relaxation
  4.    None of these
 Discuss Question
Answer is Option A. -> Spin - lattice relaxation

 Discuss Question
Answer is Option B. -> 10.05
Answer: (b).10.05
Question 9. Why is it important to use a deuterated solvent?
  1.    NMR uses least of this solvent
  2.    So the spectrometer can lock onto the sample to prevent the spectrum from drifting during aquisition
  3.    Expensive solvents work best with NMR
  4.    They dissolve polymer the fastest
 Discuss Question
Answer is Option B. -> So the spectrometer can lock onto the sample to prevent the spectrum from drifting during aquisition
Answer: (b).So the spectrometer can lock onto the sample to prevent the spectrum from drifting during aquisition
Question 10. What does the Michelson interferometer do?
  1.    Split a polychromatic beam of radiation into its component wavelengths
  2.    Selectively filter certain wavelengths from a beam of I.R. radiation
  3.    Modulate the I.R. signal at a lower frequency, so that it can be observed by a detector
  4.    none of the above
 Discuss Question
Answer is Option C. -> Modulate the I.R. signal at a lower frequency, so that it can be observed by a detector
Answer: (c).Modulate the I.R. signal at a lower frequency, so that it can be observed by a detector
