The Chinese edition of Spectroscopy and Spectral Analysis was founded in 198 1, which is the source periodical of Statistics of Scientific Papers in China, Abstracts of China Academic Journals, Wanfang Database and Tsinghua University Tongfang Database.

It has been included in China's physical and chemical core journals of natural sciences, such as Chinese Science Citation Index (CSCI), American Chemical Abstracts (CA), American Engineering Index (Ei), Russian Abstracts Magazine (рФ), MEDLINE and American Science Citation Index (SCI). It's not a journal included in Sci.

Emission spectrum:

The emission spectrum can be divided into three different categories: linear spectrum, band spectrum and continuous spectrum. Linear spectrum is mainly produced by atoms, band spectrum is mainly produced by molecules, and continuous spectrum is mainly produced by incandescent solid or gas discharge.

There are millions of spectral lines emitted by atoms observed in modern times. Each atom has its own unique spectrum, just like a human fingerprint. According to the theory of spectroscopy, each atom has its own series of discrete energy states, and each energy state has a certain amount of energy. Taking the hydrogen atom as an example, energy can be expressed as.

In the formula, n is a positive integer from 1 to ∞, which is called the principal quantum number. From a classical point of view, n describes the orbital size of electrons around the nucleus. Each value of n also determines an energy level. RH is Rydberg constant of hydrogen atom. H is Planck constant. The negative sign in the formula is because it is customary to set the energy corresponding to n=∞ as the highest value to make it equal to zero.
