As a typical oscillating chemical system, the frequency characteristic of photochemical oscillatory system is analyzed by a reliable oscillation frequency spectrum (OFS) approach. The results show that every periodic signal have a special OFS. The relative standard deviation (RSD) values of frequencies of four relative oscillating signals which belong to photochemical oscillatory system are extracted. They have multi-frequency characteristic. OFS successfully realizes the extraction and calculation of photochemical oscillatory system. OFS can be used to analyze the frequency of complex periodic signal accurately and be suitable for many areas. [ABSTRACT FROM AUTHOR]
