Description

Electron diffraction study of neodymium triiodide molecule structure is carried out. It is found that the molecule has D3h symmetry and equilibrium value of internuclear distance Re(Nd-I) = 286.6(5) Pm. The measured values of root-mean-square vibration amplitudes and experimental values of valency frequencies permit evaluation of deformation frequencies

Abstract (Russian)

Выполнено электронографическое исследование строения молекулы трииодида неодима. Найдено, что молекула имеет симметрию D3h и равновесное значение межъядерного расстояния Re(Nd-I) = 286,6(5) пм. На основе измеренных значений среднеквадратичных амплитуд колебаний и экспериментальных значений валентных частот оценены деформационные частоты
