- Can you explain spectroscopy? Let's start with NMR Spectroscopy. What is the difference between a proton being enantiotopic and homotopic? What does it mean for a proton to be shielded or deshielded? How do you determine J (the coupling constant)? What does 'coupling is mutual' mean? How is that translated on the NMS Spectroscopy spectrum? Does that have to do with the polarity of the molecule? Is there an easier way to explain that? When thinking about C-13 NRM Spectroscopy, what it meant by the statement, "the carbons cannot integrate"? When looking at an NMR Spectroscopy spectrum, how do you know which peak belongs to which proton? (The intensity of the peak and the ppm of the peak) P.S. These questions come from after watching a lecture. There is no graded assignment attached to these questions. I simply do not understand the material.List all peaks and multplicity in this NMR Spectrum in addition to what possible compound it can be.This is referring to infrared spectroscopy. Why does the first double bond have a weak/non-existent peak while the second double bond has a moderate intensity peak?
- Metion the various reason for which NMR spectrum can be Broaden? ( please do not copy paste from internet , please write in simple language so that I can easily understand , please mention atleast 6 to 7 reason , please point wise give detail explanation , do not give short cut plz ) give answer point wise point 1 point 2 like this 6 points with explanation plz. If you have answered earlier plz do not answer again .Show how the NMR spectrum of 2-bromo-2-methylbutane would look like, include approximate chemical shifts, integration ratios, and signal multiplicity. Briefly state your reasoning so i can understand better, thanks!C13 HNMR Spectroscopy, please solve this problem and explain it..
- Hi, can anyone solve thes for me with a detailed explanation. I am having a hard time understanding NMR spectroscopy, hence it would be a great help if you could answer these with detailed explanation.what is their relationship, and will this matter when you look at the NMR?Can someone help me draw a sketch of the predicted NMR of this compound thank you.
- First structure determination of a synthetic organic molecule, what is the utility of a standard, proton-decoupled carbon spectrum? In this context, or integrals and couplings useful in a carbon spectrum? Why or why not?Using a 300 MHz NMR instrument:a. How many Hz downfield from TMS is a signal at 2.5 ppm?b. If a signal comes at 1200 Hz downeld from TMS, at what ppm does it occur?c. If two signals are separated by 2 ppm, how many Hz does this correspond to?What are the different names for 2D NMR experiments and what are they used for?
