Question
Chapter 3, Problem 3.2QAP
Interpretation Introduction
Interpretation:
CMRR of amplifier is to be calculated.
Concept introduction:
CMRR stands for Common Mode Rejection Ratio. It represents how effectively the common mode signal (for example -noise) is rejected by a difference amplifier.
The formula to calculate CMRR is
where Ad and Ac represents difference mode and common mode gains of the difference amplifier respectively.

5 (a). Using the peak information you listed in the tables for
both structures, assign each peak to that portion of the
structure that produces the peak in the NMR spectrum. Draw
this diagram on your own sheet of paper and attach the sketch
of your drawing to this question.

- Interpreting NMR spectra is a skill that often requires some amount of practice, which, in turn, necessitates access to a collection of NMR spectra. Beyond Labz Organic Synthesis and Organic Qualitative Analysis have spectral libraries containing over 700 1H NMR spectra. In this assignment, you will take advantage of this by first predicting the NMR spectra for two closely related compounds and then checking your predictions by looking up the actual spectra in the spectra library. After completing this assignment, you may wish to select other compounds for additional practice. 1. Write the IUPAC names for the following two structures: Question 2 Question 3 2. Predict the NMR spectra for each of these two compounds by listing, in the NMR tables below, the chemical shift, the splitting, and the number of hydrogens associated with each predicted peak.

To check your predictions, click this link for Interpreting NMR Spectra 1. You will see a list of all the - compounds in the spectra library in alphabetical order by IUPAC name. Hovering over a name in the list will show the structure on the chalkboard. The four buttons on the top of the Spectra tab in the tray are used to select the different spectroscopic techniques for the selected compound. Make sure the NMR button has been selected. 4. Scroll through the list of names to find the names for the two compounds you have been given and click on the name to display the NMR spectrum for each. In the NMR tables below, list the chemical shift, the splitting, and the number of hydrogens associated with each peak for each compound.
