A potentially useful scheme for photoselective isotope enrichment is presented. The selective laser excitation step is accomplished by utilizing the Stark effect to shift molecular transitions into resonance with laser frequencies. The method is demonstrated for isotope separation of /sup 13/C, /sup 15/N and /sup 2/H. Laser Stark spectroscopy can sensitively detect as few as 10/sup 9/ molecules in the optical path, thus the isotopic separation can be achieved from industrial sample mixtures containing natural abundances. A comparison of the isotopic enrichment efficiency using the present method of ''exact'' resonance and the previously used method of ''near'' resonance excitation is also given.
