Assign each of the following statements with the corresponding type(s) of spectroscopy. Note that some statements...
Which of the following statements is FALSE ? Atoms undergo electronic transitions but not rotational or vibrational transitions B Typically, IR radiation causes vibrational transitions of molecules O c Compared to IR, UV radiations have longer wavelengths and less energy D Shorter the wavelength of a radiation higher the frequency
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...
