NMR

Question 1

Resonance=

Answer 1

• Process where the nucleus absorbs energy and rapidly flips between two spin states. Energy is in the form of Radio waves which causes flipping.

Question 2

Chemical shift

Answer 2

• the frequency radio waves and energy needed to cause magnetic resonance
• Due to the number of electrons.

Question 3

Standard Peak

Answer 3

• TMS (Tetramethylsaline)
• Has a chemical shift of 0
• non-toxic, inert liquid
• low bp, can be distilled off and reused
• 12 H atoms so a lot of energy required
• all C&H atoms in same environment so only 1 peak
