Major structural difference between Morphine and Heroin is presence of Hydroxyl group in morphine vs ester group in Heroin.
In case of morphine, a broad weak peak at 3300 cm-1 can seen which would be absent in Heroin.
In case of heroin, peak of medium intensityyat around 1750 cm-1 can be seen which would be absent in morphine.
These two significant differences in the molecules would be visible. Remaining spectra would be similar.
6. What would be the expected differences in the Raman spectra of heroin and morphine? HO...
What four structural features do all of these opioid drugs have in common? Codeine, morphine, heroin, oxycodone, oxymorphone, hydromorphone, meperidine, methadone, buprenorphine, naloxone.

(i) Describe with appropriate diagrams, the concept of Raman scattering spectroscopy. Name 2 primary differences between Raman and Infra-red spectroscopy. What is the fundamental property of a molecule that is probed by Raman scattering? [6 Marks] (ii) What are the three possible deviations from the Beer Lambert law? Explain why they might arise. Give an example using chemical equations of a deviation in the Beer Lambert Law due to a chemical shift. [

what are the allowed symmetry transitions for PF5 for UV (3) and raman (6)?
IR Spectroscopy of Aspirin 1. Draw the structure of aspirin and state the chemical name of aspirin. 2. Indicate the regions (circle and label on your IR spectrum) of your spectrum that correspond to a carbonyl and a hydroxyl functional group. Identify two other regions that correlate with other functional groups/structural features. Indicate these regions on your spectrum (circle and label on your IR spectrum). 3. Use your IR spectrum, melting point data, and FeCly test results to characterize the...
