On the hydrogen spectrum of atomic spectrum
Atomic spectrum is a key way to explore the microstructure of matter. Among them, the spectrum of hydrogen atoms, because of its simple structure, plays an important role in spectral research.
The spectrum of hydrogen atoms shows a specific spectral line law. When a hydrogen-containing gas is excited by high voltage or high temperature, the hydrogen atom is energized, and the electron jumps to a high energy level. However, this state is unstable, and the electron jumps back to a low energy level. During the process, energy is released in the form of photons to form a spectrum.
Its spectral lines have discrete characteristics and are not continuously distributed. This is contrary to the classical electromagnetic theory. According to the classical theory, the movement of electrons around the nucleus should continuously radiate energy, and the spectrum should be continuous. However, the discrete spectral lines of the hydrogen atom show that the electron energy in the atom has the characteristics of quantization, that is, it can only take specific discrete values.
After many scientists' studies, such as Balmer and Rydberg, the empirical formula describing the position of the spectral lines of the hydrogen atom has been summarized. Take the Balmer system as an example. The spectral line is in the visible light region, and its wavelength satisfies a specific mathematical relationship. This formula can not only accurately describe the known spectral lines, but also successfully predict the unknown spectral lines, demonstrating the strong guiding significance of the theory.
The study of the spectrum of the hydrogen atom laid the foundation for the birth of quantum mechanics. It revealed that the microscopic world and the macroscopic world follow different physical laws, prompting scientists to re-examine the nature of material structure and interaction, which greatly promoted the development of physics. The in-depth investigation of hydrogen atomic spectroscopy helps us to understand the atomic structure more clearly, providing important examples and theoretical support for subsequent elemental and molecular spectroscopy studies.
