The LPM suppression of photon emission rates from the quark gluon plasma havebeen studied at different physical conditions of the plasma given bytemperature and chemical potentials.The integral equation for the transversevector function (f(p_t)) consisting of multiple scattering effects is solvedfor the parameter set {p,k,kappa,T}, for bremsstrahlung and AWS processes. Thepeak positions of these distributions depend only on the dynamical variablex=(T/kappa)|1/p-1/(p+k)|. Integration over these distributions multiplied byx^2 factor also depends on this variable x,leading to a unique global emissionfunction g(x) for all parameters. Empirical fits to this dimensionless emissionfunction, g(x), are obtained. The photon emission rate calculations with LPMsuppression effects reduce to one dimensional integrals involving folding overthe empirical g(x) function with appropriate distribution functions and thekinematic factors. Using this approach, the suppression factors for bothbremsstrahlung and AWS have been estimated for various chemical potentials andcompared with the variational method
