- how molecular spectroscopy work?Discuss IR Spectroscopy theory: how does it work on a chemical level? What are the different regions of an IR spectra? What does it tell us about the molecule? 2.Discuss any chemical effects that may alter peak regions, specifically resonance.Explain Infrared Spectroscopy?
- 5. A sample of a red dye and a sample of a blue dye both have the same concentration. Their Absorbance is measured using the same spectrophotometer. At a particular wavelength, will both samples give the same Absorbance reading? Why or why not?Compare 1D Nucletic Magnetic Resonance (NMR) and 2D NMR? Please answer at your own easy words. Answer should be to the point.10) For each spectrum, give the following: What type of spectroscopy produces a spectrum that looks like that What type or types of energy transitions are involved (i.e. electron going from one atomic orbital to another, molecule going from a lower vibrational state to a higher vibrational state, etc.) What quantum mechanical model or theory provides a description for the type of spectroscopy (i.e. harmonic oscillator model, molecular orbital theory, etc.) What part of the electromagnetic spectrum is absorbed or emitted by the energy transitions for the type of spectroscopy Describe what information this type of spectroscopy can give us about an atom or molecule and how the spectrum is interpreted
- Infrared spectroscopy is most useful for Please choose the correct answer from the following choices, and then select the submit answer button. Answer choices determining the molecular structure of an unknown compound. differentiating between functional groups. determining the exact chemical formula of an unknown compound. determining the molecular mass.Explain why this is the correct spectra for these molecules. Identify a specific absorption band which identifies each characteristic functional group of the chosen molecule.6. Provide two possible Lewis structures for the formula: C,H,O (For help, you may want to review the material in the next lab or Chapter 12, section 4 in your textbook). Dbe ress ic the h d peccop ecomputer-bas appear to be Remember that signals in IR spectroscopy are due to bonds vibrating.
