The equilibrium structure, the potential energy surface and the infrared harmonic frequencies are determined by using two generalized gradient approximation density functional methods for methylamine. The results are compared to those of a second-order Moller-Plesset and coupled cluster calculations

β¦ Synopsis
Near Hartree-Fock calculations with carefully optimized basis sets of gaussian lobes are performed for the different possible geometries of CH! _ Equilibrium bond lengths and angles are calculated in ever) case. The equilibrium geometry correspon a s to one of two possible structures lvith C, symmetry between which there is almost free rotation. The potential hyper-surface has local minima of Cqv symmetry and saddle points of l&h and CT!, symmetry. Binding energies, orbital energies, bond lengths and dipole-moments are tabulated.
