Study Notes

Analytical Chemistry

The craft of analytical chemistry involves identifying and quantifying the chemical components of a substance

Spectroscopy

Spectroscopy is the study of the interaction between matter and electromagnetic radiation
It gains information about a material by measuring how it absorbs, emits, or scatters electromagnetic radiation

Electromagnetic Radiation

Electromagnetic radiation consists of photons, which are massless particles with both wave-like and particle-like properties
Electromagnetic radiation travels through a vacuum at a velocity of approximately 299,792,458 meters per second
The energy of a photon is directly proportional to its frequency, and inversely proportional to its wavelength or wavenumber (E = hc/λ)

Interaction between Sample and Electromagnetic Radiation

The interaction between a sample and electromagnetic radiation is easiest to understand in terms of the optical properties of electromagnetic radiation
When electromagnetic radiation passes through a sample, it is absorbed, emitted, or scattered by the molecules in the sample, providing information about the sample's composition
Characterization of the composition of matter is achieved by analyzing the changes that occur in the electromagnetic radiation as it interacts with the sample
