The ESEEM spectroscopy was used to determine positions of the Nd impurity ions in YSiO single crystal. It is established that neodymium ions substitute yttrium ions in the Y2 positions with seven nearest oxygen ions. Crystal field parameters of Nd impurity centers in isotopically pure YSiO and ScSiO single crystals were determined using data of CW EPR spectroscopy and the known energy level schemes.
