  The carriers of diffuse interstellar bands are still mysterious species.
There exist many arguments that diffuse bands at 5797 and 5850 angstroms have
the same carrier. Using high-resolution spectra of few dozens of reddened stars
we have searched mutual correlation between intensities of considered bands.
Results of our analysis indicate that 5797 and 5850 really tend to have the
same carrier.
