Abstract Single crystalline specimens of RNi2B2C (R=Y, La) and Y(Ni.7Co.3)2B2C (non-superconducting reference) have been isolated from polycrystalline samples and successfully orientated. All four observable Raman peaks could be measured and unambiguously be attributed to vibrations of B and Ni atoms. Most important, we can show that a broadening of the B-A1g mode also occurs in non-superconducting reference samples and should therefore not be taken as an evidence for a dominant role of the B-A1g mode in the pairing interaction.
