It is pointed out that the only possible artifact, free opticalNMR (ONMR) shift of up to 0.1Hz reported by Warrenet al. [1] is the same precisely, 0.1Hz, as that predicted byB ³ theory. However, the great majority of the data by Warrenet al. are almost completely artifactual and cannot be used to discriminate between differentONMR mechanisms with any objectivity. Some references toB ³ theory andrecent ONMR data uncited by Warrenet al. are pointed out, data which show that the Warren group–s failure to see very well known [2,3] polarization-dependent effects of irradiation inNMR is a major design failure, not one of theory.
