The noncoincidence effect in the ngr;3band of liquid methyl fluoride

摘要

The 11 cmminus;1splitting observed in the ngr;3region of the Raman spectrum of liquid methyl fluoride is explained as arising from the noncoincidence effect. An interpretation of the solidhyphen;state infrared and Raman spectra is based upon correlationhyphen;field splitting effects. An analysis of these two effects suggests that the transitionhyphen;dipole moment increases from 1.31times;10minus;6Cthinsp;kgminus;1/2in the gaseous state to 2.28times;10minus;6Cthinsp;kgminus;1/2in the solid state.
