A modified valence-force-field (VFF) model is applied to the lattice dynamics of trigonal selenium. Five adjustable parameters, four valence-force-constants (K_r, K_θ, K_<rr'>, K_<rθ>) within intra-chain couplinge and one inter-chain force constant (K_R), are determined from the observed six elastic constants by mans of the least squares method. By using these fore constants, comparable fits to the Г-point optical frequencies for the A_1, E_1 and E_2 modes are obtained except that for the A_2 mode. However, the last can be also accounted for well if the contribution of about 50 cm^<-1> from the long-range electrostatic interaction is taken into account. The estimation of the above contributin seems reasonable from the view-point of the shell model analysis due to Chen and Zalldn [Phys. Rev. 173 (1968) 833]. In conclusion, the modified VFF employed here reflects the bonding in trigonal Se fairly well.
