The aim of this work is to implement time dependent Quantum mechanical approaches to study inversion phenomena of ammonia Molecule. This approaches will enable us visualize the time evolution of the orientation of the molecule inside the symmetric double well potentials. To study this approach diffusion Quantum Monte Carlo(DQMC) method, which propagates the time dependent Schrödinger equation in imaginary time, had been used.
