- 5. Did you have unknown A or B? Which unknown does your NMR indicate that you isolated and how do you know (include what types of chemical shifts led you to this conclusion)? Include your worked up (MestreNova: peak pick, integrate, normalize, and reference to chloroform or DMSO) and annotated (assign the peaks) NMR to the worksheet for this question. You must do the work up yourself, any copying or using of worked up data from another student is academic misconduct.
