Chemistry 14CL Winter 2016 Experiment #15: Nuclear Magnetic Resonance Spectroscopy Pre-lab Report MUST be written inside the lab notebook Online Resources and Tutorials What Nuclear Magnetic Resonance Can Measure Principles of Nuclear Magnetic Resonance Applications of 13 C NMR. Pre-lab Report Guidelines (1) Title of the experiment & introduction (2) Procedure in Flowchart Format & Reference (3) Pre-lab study questions Complete ALL the study questions on page 139 of your lab manual (MUST SHOW ALL YOUR REASONINGS IN ORDER TO RECIEVE FULL CREDIT) Note: There are TWO signals around 130 ppm in spectrum 1 on page 137 of the lab manual. Also ignore any signal that appears at 0ppm. Use the DEPT table on page 144 (or the one on the lecture guide) when answering question #3 of the study question. Remember that in DEPT spectroscopy, carbons with no hydrogen attached give no signals on the

Unformatted text preview: DEPT spectra. Chemistry 14CL Winter 2016 Experiment #15: Nuclear Magnetic Resonance Spectroscopy Post-lab (This post-lab is due at the END of the NMR Spectroscopy Workshop) Turn in ONE Post-lab Per Group Your Post-lab is the COMPLETED NMR WORKSHEETS (will be provided in the lab). (1) Write the names of your group members on EACH page of the worksheet. (2) Answer questions (1) - (3) in lab (see page 139) Note: for question #3, your group needs to PREDICT the 13 C, DEPT 45 & 90 spectra for EACH of the isomer. (3) Answer questions (4) - (6) in the computer lab (see page 139 & 140) Note: for question #6, your group need to COMPARE your predicted 13 C, DEPT 45 & 90 spectra with the computer generated spectra for EACH of the isomer. Staples all the worksheets (if you take them apart during the lab period) and turn them in to your TA at the end of the lab period....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
