Carbon is a common impurity, present as an acceptor, in GaP. The fundamental of the local vibrational mode of <sup>12</sup>C in GaP has been identified at 606.2 cm<sup>-1</sup> at 20 K and the identification has been confirmed by investigating the isotope shift in <sup>4</sup>C-doped crystals. An earlier tentative identification of a gap mode of As in GaP at 270.0 cm<sup>-1</sup> at 20 K has been confirmed.
