Precision spectroscopy

Precision spectroscopy is a scientific technique used to measure the properties of atoms and molecules with extremely high accuracy. By analyzing the light they absorb or emit, scientists can determine their exact energy levels and structures. This helps in testing fundamental physical theories, detecting tiny changes in physical constants, and developing new technologies like atomic clocks. Essentially, precision spectroscopy acts like a highly detailed fingerprinting method for atoms and molecules, providing insights into the universe’s fundamental properties with remarkable accuracy and stability.
