| Question | Answer |
| Fermi Resonance | Artificial amplification of a frequency due to constructive interference of a nearby peak. |
| DOU Calculation | Degree of Unsaturation caused by pi bond or ring. DOU = C - 1/2X + 1/2N + 1. Where X = Monovalent atoms (H or halogens) and N=trivalent atoms (N or P). |

| C-Cl | 800-600 |
| C-F | 1400-1000 |
| N=O (Nitro: R-NO2) | 1300-1600 |
| C triple bond N (Nitriles) | 2260-2240 |
| N-H | 3500 |
| O-H (Carboxylic Acids) | 3300-2500 |
| O-H (Alcohols, phenols) | 3200-3650 |
| C-O (Alcohols, ethers, esters, carboxylic acids) | 1300-1000 |
| C=O (Aldehyde) | ~1710 |
| C triple bond C (Alkyne) | 2250-2100 |
| C=C (Alkene) | 1680-1600 |
| C-H, Alkenes, Aromatics, Alkynes, Aldehydes | ~3000 |
