Study Of Solution Concentration Influence On The CS₂ Fermi Resonance Effects By J.E, Bertran Method

Fermi resonance is a widespread phenomenon that present in the inter and intra molecular vibration coupling and energy transfer . intra Fermi resonance is the coupling of a fundamental frequency with a combination frequency or a overtone frequencyFermi resonance is an important phenomenon. in research of composition and structure of molecular, and have an important theory means and application of this research.This study introduced the Fermi resonance quantum theory, also introduced the methods of Fermi resonance research -- Transform solvent method and given the parameters of Fermi resonance:intensity ratio of two line R , Energy Width ? , Inherent energy width ? 0, Coupling coefficientω,Anharmonic force constants K This paper describes the Fermi resonance nature of the p-benzoquinone by infrared spectra methods.The innovative work of this paper :1): study the Fermi resonance of CCl4 by Raman methods calculated generated including f symmetric stretching vibrations2): Of C H CS2 Fermi resonance, with its concentration of CS2 Fermi resonance parameters (R, W,, K) changesThis paper should also further work(1) Fermi molecular resonance studies.(2) certain Fermi resonance of theoretical study and the theory has been revised and improved.
