RAMAN STUDY OF BENZENE NEAR THE MELTING POINT
Preview AbstractWe calculate here the Raman frequencies of some lattice modes as a function of pressure at constant temperatures for the solid and liquid phases of benzene. The observed data for the molar volume from literature is used to calculate the Raman frequencies through the mode Grüneisen parameter in benzene.
Our calculated frequencies are in good agreement with the observed data when the mode Grüneisen parameter is taken as a constant at one particular pressure in solid benzene.
It is shown here that the Raman frequencies can be calculated from the volume data, as demonstrated for benzene here.
