Name Lab SectionDate LAB REPORT Organic Spectroscopy STRUCTURE OF UNKNOWN (Draw Below Code Numbar 11 10 2 PROTON MAGNETIC RESONANCE SPECTRAL DATA Complete the table below by listing the chemical shifts of all of the signal patterns in the nme spectrum of your compound (chemical shifts of clear muitiplets are sinals numbers at the midpoint of the patten, chemical shifts of complex multiplets are given as ranges). Assign the multiplicity (singlet, doublet, triplet·quartet. ote. or complex muhiplet as appropriate). Give the integration values (whole number tatu from integration trace on your spectrum). Finalily give your assignment for sach signal; do this by designating each signal pattern by letters, A. B, C, etc, and using these letters to label the different sets of protons in the structure you have drawn in part 1, above CHEMICAL SHIFT MULTIPLICITY NTEGRATOl ASBGMENT 3. INFRARED SPECTRAL DATA from the intrared spectrum you ran. List the Fill in the lable bølow using data specilic frequencies for those characteristic absorptions which can be assigned for your compound (round values off to nearest whole wave number). Consdeing the % ransmittance values of the peaks reported, assign their appearance as strong, weak sharp, broad, etc., as appropriate. In the third column list the specific vibrational assignment made for each absorption reported (.o., sp C-H stretch; CO stretch: Aryl C-H out-of-plane bend for o-disubstituted benzene; otc) FREQUENCY (cm) APPEARANCE ASSIGNVENT
