A - CI6.2 Radiation interacting with Matter

When absorbing energy the molecule can behave in different ways:

• translation - whole molecule moving
• rotation - of the whole molecule
• vibration - of the bonds
• electron energy

Increasing energy needed:

Translatinonal > Rotational > Vibrational > Electronic

• Electronic energy changes as electrons move energy levels - elecrtonic energy is quantised with fixed levels
• ALL…
