Which of the following is NOT true about infrared spectroscopy? (a) when molecules absorb IR bonds start vibrating with greater amplitude (b) when molecules absorb IR electrons jump to higher energy levels (c) polar bonds show greater IR absorbances than non-polar bonds (d) IR radiation is lower in energy than uv radiation
In order for a molecule to absorb IR light the ________ must change during a vibrational mode. Can N2 absorb IR light? Can HCl absorb IR light?
True or False 1. A strong signal in infrared spectroscopy indicates that a molecule matches the emitted electromagnetic radiation and reports a high transmittance. 2. Among all the possible vibrational modes, symmetric stretching will be IR inactive. 3. A hygroscopic organic sample to be subjected to IR does not need to be kept dry because water molecules in the air will not affect the IR spectra.
Which of the following statements about the IR activity is true? A linear diatomic molecule composed of two identical atoms has a reduced mass of zero resulting in an infinitely high natural frequency of vibration. A linear diatomic molecule composed of different atoms will not have any IR active stretching mode. Degenerate IR active modes have the same natural frequencies of vibration A non-linear molecule composed of 17 atoms will have 45 active IR vibrational modes. IR vibrational modes typically correspond to a change in a dipole moment that is perpendicular to one of the molecules mirror planes.
