Landau-De Gennes Model of First Order Transitionsl exponents” are calculated. In MFA, the specific heat exponent α’ = 0.5 while in GA, α = 0.5, in agreement with experimental findings in nematic-isotropic (N-I) transitions of liquid crystals. However, in GA, the exponents on the two sides of T., are not equal to each other in general. For example,

All transition among various phases are second order. For some special cases our results reduce to the known results or to the exact solutions.

On the other hand, the oscillating dipoles Nb-0 associated with the unstable mode are strongly correlated along the <100> directions; the dipole-dipole coupling explains the strong anisotropy of the TA and lowest TO phonon branches as well as the x-ray diffuse scattering planes.
