Frequency-domain spectroscopy

Frequency-domain spectroscopy is a technique that analyzes how materials respond to different frequencies of electromagnetic waves, such as light or radio waves. Instead of looking at how a material absorbs or transmits radiation over time (time domain), it measures the response across a range of frequencies at once. This provides detailed information about a material's properties, like molecular structure or composition. By examining how the material interacts with various frequencies, scientists can identify substances, study their characteristics, or detect changes in their environment. It’s a powerful tool for understanding materials at a fundamental level.
