Interatomic force constant ($alpha@) of the A-C and B-C bonds in A$+II$/B$+IV$/C$-2$/$+V$/ and A$+I$/B$+III$/C$- 2$/$+VI$/ groups of optoelectronic materials has been calculated using plasma oscillations theory of solids. A new relation between force constant and plasmon energy has been obtained. The effect of delocalization of noble metal d- electrons has been taken into account while calculating the force constant of the A-C bond in A$+I$/B$+III$/C$-2$/$+VI$/ semiconductors. On the basis of the best-fit data, another simple equation has been proposed for the calculation of the force constant from their plasmon energy. The calculated values of force constant from these equations have been compared with the values reported by different workers. An excellent agreement has been obtained between them.
