3) Infrared spectroscopy: Lur Iran 3325 IR Spectrum (liquid film) 4000 3000 1200 800 2000 1600 V (cm:') a) Are there any peaks between 4000 сm land 3100 cm-?? If yes, what does the peak correspond to and what does it tell you about the structure? If no, what does this tell you about the structure? 1 Mark b) Look carefully at the peaks clustered around 3000 cm 1. I. Are there any signals just above 3000 cm-- ? What do these correspond to and what do they tell you about the structure? II. Are there any signals just below 3000 cm-1? What do these correspond to and what do they tell you about the structure?
1 Mark c) Are there any peaks between 2500 cm - and 2000 cm?? If yes, what does the peak correspond to and what does it tell you about the structure? If no, what does this tell you about the structure? 1 Mark d) Are there any STRONG peaks between 1800 cm-1 and 1600 cm-?? If yes, what does the peak correspond to and what does it tell you about the structure? If no, what does this tell you about the structure? 1 Mark INITIAL FRAGMENT SUMMARY: Summarise what you know so far about the structure by drawing fragments or functional groups you know or suspect are present in the molecule: 2 Marks
