1. Explain how each spectroscopy (IR, Mass spec, and NMR) method works- what are you observing? What is happening to the molecule that gives rise to useful information. 2. Explain how to read each: IR, NMR, mass spec. 3. Why are -OH and -NH signals in both proton NMR and the IR region relatively broad in appearance? Explain how the appearance of the -OH stretch would change in the IR spectrum of an alcohol was take in the gas phase...

In 19F NMR spectroscopy, the F nuclei behave just like protons in 1H NMR spectroscopy in that they have a nuclear spin quantum number of 1/2. How many 19F NMR resonances do you expect for PF5? (Assume a static structure. In other words, the axial and equatorial do NOT rapidly scramble and change positions on the timescale of the NMR experiment.)

State the theory and explain how NMR and IR spectroscopy work.

Explain the proper techniques for cleaning the NMR tubes. Explain NMR and IR spectroscopy and what can be gained from both individually to analyze an unknown sample. Explain and show work.

what is meant by stokes shift and anti stokes shift in spectroscopy?

Difference between Mass Spectrometry, Infrared spectroscopy(IR), & nuclear magnetic resonance spectroscopy(NMR)?

2. Use either a shift in demand OR a shift in supply (not both) to GRAPHICALLY represent each of the following situations. Also, label the graphs correctly and indicate the changes in equilibrium in each case. a) The avocado market: Widely publicized studies on the health benefits of avocado consumption. b) Crude oil market: Interruption of world supplies as a result of the war in the Middle East. c) Orange Juice Market: Increased imports of orange juice from Brazil. d)...

For an NMR(Nuclear Magnetic Resonance) Spectroscopy (proton NMR), 1.What is meant by chemically equivalent protons? 2.What is meant by chemical shift proton? 3.How can you tell whether two protons are chemically equivalent? Also, 4. Difference between enantiotopic, diastereotopic, and homotopic protons?
