I need help with mass spectroscopy.

Scan 161 (4.901 min): SPARKY.D Add itional m/z abund. 152127.1 C344 Spectroscopy Problem Set Answer Sheet for page \# 1. With a molecular formula of the degree of unsaturation is calculated as 2. The structure of this molecule is 3. IR (cm1 ) List all notable R peaks and label each representative R stretch if possible (ie. alcohol, C=0, etc). Peal Grou 4. List all 1HNMR peaks given in the problem in the proper format. ex.1HNMR(500MHz,CDCl3)7.26(m, 1H), etc. Some of the splittings are difficult to determine initially and may only be found after the structure is solved. 5. List all 13C NMR peaks given in the problem in the proper format. Ex. 13CNMR(125MHz,CDCl3)72.4(t, 1C). Some of the splittings are difficult to determine initially and may only be found after the structure is solved. 5. Correlate peaks in the mass spectrum to possible molecular fragments of the parent molecule. Ex: M18= dehydration (loss of water) ORm/z=57 is the t-butul carbocation, m/z=77 is the phenyl cation.
