We present an improvement to the self-consistent field (SCF) scheme for coupled vibrations, assuming that the correction to the SCF wavefunction can also be approximately written as a product of single-mode functions. This defines a self-consistent correlations method, whose computational effort scales linearly with the mode number. We test the method by a series of model computations on nonbending triatomics in local coordinates. The scheme seems to be simple and general for correcting SCF wavefunctions for coupled anharmonic vibrations.
