H3 Chem Spectroscopy Tutorial Answers

The answers have been sent to the photocopy shop today, and will probably be available late tomorrow. I've also included tables of data for NMR chemical shifts and IR absorptions.

In addition for Part 2 Question 4(the UV question) you need to plot the curve accurately and becareful of unit conversions and scaling factors for original sample against diluted standard aliquots. I've only given the numerical answer though.

Students wonder whats important about NMR; the following are key things, 1) Intepretation of NMR spectra - this is the most important and requires practice. 2) theories behind deshielding effects, anisotropy, electron withdrawing effect. 3) behaviour of labile protons with D2O and with CDCl3, i.e, in protic versus aprotic deuterated solvents.

cheers and all the best.
