Determination of the Belomestnyh-Tesleva’s formula from the Gr"uneisen’s equation

From the well-known Grüneisen equation the derivation of the Belomestnykh- Tesleva’s formula, which establishes an unambiguous connection between Poisson's ratio and the Grüneisen’s parameter, is proposed. The Belomestnykh-Tesleva formula, obtained earlier from other initial premises, using the theory of elasticity and the Leontiev equation is derived. The proposed approach finds quite satisfactory agreement with experimental data for a number of silicate glasses and glassy met phosphates of alkaline earth metals.
