Abstract
A simple and inexpensive experiment is described which detects magnetic field effects on chemical reactions with high signal-to-noise ratio and high resolution. It consists in applying a small modulation field to the sample, whilst the main field it experiences is varied, with optical detection at the modulation frequency. It consequently measures the derivative of the normal MARY spec­ trum. It is shown by theoretical analysis that when using this method it is better to monitor reaction intermediates than products. The method is demon­ strated by application to known systems in which additional features are some­ times observed, in particular a low-field featur...
