A laboratory computer interface with an electron spin resonance ESR spectrometer is reported, which permits operator control of the magnetic field through the computer. Two programs are described. In the first, the field is stepped and checked for stability at pre-set increments before data from a signal channel and a reference channel are collected. Any number of increments can be accumulated, and the signal channel can also be recorded as a function of time. The second program uses a continuous sweep to collect data. Sweep rates up to 10 KGmin have been used. No auxiliary coils are used. The data acquisition program is started by signal from the reference channel, and the reference absorptions are counted on the return sweep to insure reproducible starting fields. Signals from the reference or from the sample channels can be recorded during a sweep. Both programs are sufficiently open so that other peripheral functions can be executed. Author
