Which of the following statements about IR spectroscopy is most FALSE?
Which of the following statements about IR spectroscopy is most FALSE?
A C-H bond vibrates at a higher frequency than a C-C bond.
bonds in molecules vibrate at set frequencies
In an IR frequency is absorbed, the observed transmittance % will decrease
IR spectroscopy analyzes the spin of atomic nuclei in a molecule
Homework Answers
Correct option:
IR spectroscopy analyzes the frequency of vibrations of bonds in a molecule. It has nothing to do with nuclear spin. The statements in other options are true.

Which of the following statements about IR spectroscopy are true? Check all that apply. The frequency of vibration depends on the mass of the atoms on either end of the excited bond. A common light source used to generate light of IR wavelengths is a tungsten filament lamp. The type of bond (single, double, triple) has no effect on the energy required for excitation in IR spectroscopy. The potential energy of bond oscillation is affected by Coulombic repulsion when the...

Indicate which of the following statements about the electromagnetic spectrum and IR spectroscopy are true and which are false. In any cases where the statement is false, explain how or why the statement is false. Infrared (IR) light is in the gamma ray part of the electromagnetic spectrum. Electromagnetic radiation is characterized by its mass and force. UV-Vis spectra are normally scanned in the 4000-600 cm-1 region. The fingerprint region on an IR spectrum is the easiest to interpret. Stronger...

Consider the following statements regarding NMR spectroscopy. Determine whether each each statement is true or false. Spin-spin splitting can occur over many bond lengths in a molecule. NMR spectroscopy requires a nucleus having non-zero electron spin. Shielding occurs when electrons near a proton are induced to circulate by the applied field. This electron field opposes the applied field. A typical value for the chemical shift of aromatic protons is 7.5.

Which of the following events may occur when IR radiation is absorbed? (true or false) -Intra-molecular bond angles are changed. -Vibrational amplitudes of bonds are increased. -Relative electron spins are changed. -Bonding electrons are promoted to higher energy molecular orbitals. -More intense IR absorptions occur for those bonds having greater dipole moment changes with bond lengthening in a vibration.
