A spectrometer is described with particular reference to its resolution and to a novel quick change specimen holder. For the benefit of new workers in the field, the need for four‐point probe measurements is reiterated, together with the importance of suitable cleaning procedures during sample preparation and rigorous electrical screening of the spectrometer. A high resolution spectrum of benzoic acid is presented together with spectra of 1,2‐, 1,3‐ and 1,4‐benzenedicarboxylic acids. Brief mention is made of the use of a computer data acquisition system with the latter, full details being described elsewhere.
