It is shown that a channel-cut double crystal X-ray spectrometer with vertical dispersion which has the crystals in antiparallel position is suitable for absorption spectroscopy with synchrotron radiation. The utilization of the X-ray spectrometer with the pair of crystals in dispersive (antiparallel) position in the synchrotron radiation (SR) experiments has the following advantages: high resolution, utilization of the whole size of the SR source and independence of the wavelength determination of the variation of the position of the SR source. Such a spectrometer is thus advantageous for precise X-ray spectroscopic measurements in the region of short wavelengths. On the other hand, the spectrometer with the crystals in dispersive position and with the SR beam represents an overdetermined system and thus its adjustment to the SR beam is rather difficult.
