This paper presents the 3-dimensional non-LTE radiative transfer code, MOLLIE (MOLelcular Line Explorer), for solving molecular and atomic excitation and radiation transfer in a molecular gas and predicting emergent spectra. The code implementation makes use of the Accelerated Lambda Iteration (ALI) method of Rybicki & Hummer (1991) to solve the radiative transfer equation along rays passing through a spherical model cloud. When convergence between level populations, the radiation field, and the point separation has been obtained, the grid is ray-traced to produce images that can be readily compared to observations. The optimization technique, Fast Simulated Annealing (FSA), adopted by MOLLIE to increase the probability of arriving at a satisfactory output in a timely fashion, is briefly considered.
