Two sets of high-resolution spectra of RCrB obtained during the 2003 light decline are described. The first set was obtained on the descending branch of the light curve at 12.0 mag, and the second one in the recovery phase at 7.5 mag. The usual sharp and broad emissions are described and the radial velocities measured. C₂ Swan system (0,0) band was found to be in emission for the first set. The other C₂ bands were in absorption. A few CN red system (5,1) band rotational lines and low excitation FeI lines were in absorption. The measured radial velocities of various spectral features are presented.
