Spectroscopy: reading matter with light
Spectroscopy studies interactions between matter and radiation. Allowed transitions depend on the system's energy structure, providing a genuine experimental fingerprint.

Example
Hydrogen emission lines do not form a continuous rainbow: they occur at specific wavelengths tied to energy differences.
The classic trap
Do not turn a model into a literal photograph of reality. Scientific models select particular properties to explain or predict a phenomenon; knowing their limits is part of using them correctly.
Understanding check
Explain the concept to someone who knows the periodic table but not this chapter. Then give one example and one situation where the most common shortcut would become misleading.
