Q
What does a peak represent
A
E absorbed by a molecule equivalent to specific vibrational E of each bond
1
Q
Types of vibration
A
Stretching - higher E
Bending - lower E
2
Q
Peak size
A
More intense peak - more dipole
3
Q
Short, strong bonds
A
Vibrate at higher frequency - higher E
Sp > sp2 > sp3
4
Q
Light vs. heavy
A
Light vibrate faster, more E
C-H > C-C> C-N > C-O
5
Q
O-H N-H H-bonding
A
Makes bonds more rigid
Higher E
O-H > N-H
